Warhammer 40K Nova Open Preview Predictions
NOVA Open 2026 could deliver our clearest look yet at the next phase of Warhammer 40,000’s 11th Edition. The new edition has already launched with the enormous Armageddon boxed set, revised core rules, new Space Marine and Ork miniatures, updated starter products, and the first wave of faction releases.
The next major question is what comes after the launch window. NOVA Open has previously been used for Warhammer roadmaps, miniature reveals, faction announcements, and previews extending into the following year, making it a natural place for Games Workshop to outline the next stage of 11th Edition.
This preview examines the most likely Warhammer NOVA Open 2026 announcements, from the next Codex roadmap and standalone Armageddon releases to possible faction refreshes, campaign developments, and new boxed sets.
Important: This is a prediction article. Unless a reveal is specifically described as confirmed, the possibilities below are informed speculation based on announced products, unresolved previews, previous Games Workshop release patterns, and the current state of 11th Edition.

Our NOVA Open 2026 Prediction Rankings
| Prediction | Likelihood | Why |
|---|---|---|
| Updated Codex Roadmap | Very High | NOVA is well positioned to outline the next several months of 11th Edition. |
| Next Codex Reveal | Very High | Players need to know which factions follow the launch releases and Orks. |
| Standalone Armageddon Kits | High | Launch-box miniatures commonly receive separate releases later. |
| New Space Marine Release | High | Space Marines typically receive continued support throughout an edition launch. |

| Major Faction Refresh | Moderate | A roadmap may include one army receiving several replacement kits. |
| New Battleforce or Army Set | Moderate | Army sets are frequently used to launch new Codexes and model waves. |
| Completely New Army | Low | Early edition support is more likely to focus on updating established factions. |
Prediction 1: A New Warhammer 40,000 Codex Roadmap
Our strongest prediction is that Games Workshop will reveal a roadmap covering the next several Warhammer 40,000 Codex releases.
The first months of a new edition create considerable uncertainty. Players want to know when their faction will receive a Codex, whether older miniatures will be replaced, and which army will receive the next large release wave.
What the Roadmap Could Include
- The next three to six Codexes
- Approximate release seasons
- Faction silhouettes or teaser images
- Confirmation of army sets
- Hints about major miniature refreshes
- The next narrative campaign release
Why NOVA Is the Right Time
By September, the launch edition and first Codex wave will have had time to settle. Games Workshop can then shift attention from explaining the new rules to showing players what comes next.
NOVA has also previously hosted roadmap-style announcements, making a forward-looking presentation more likely than another detailed explanation of products already released.
Prediction confidence: Very high.
Prediction 2: The Next Codex After Orks
Codex: Orks was revealed during the Big Summer Preview as the first major Warhammer 40,000 Codex shown after the new edition launched. NOVA could reveal the next one or two factions in the sequence.
There are several ways Games Workshop could choose the next army:
- A faction closely connected to Armageddon
- An army with numerous older kits requiring replacement
- A popular faction capable of supporting a large release wave
- An army that received limited attention during the previous edition
- A faction that provides a contrasting playstyle to Space Marines and Orks
What to Watch For
A single character model may indicate a relatively small Codex release. A teaser showing infantry, vehicles, and multiple silhouettes would suggest a much larger faction refresh.
An army set containing a Codex and several new miniatures would also signal that the faction is receiving a substantial launch rather than a book-only update.
Prediction confidence: Very high that another Codex will be shown; lower confidence regarding the exact faction.
Prediction 3: Standalone Armageddon Miniatures
The Warhammer 40,000: Armageddon launch box introduced new Space Marine and Ork miniatures. Launch-set units are often separated into individual kits after the initial boxed product has completed its main sales window.
NOVA would be a logical place to reveal packaging, alternate builds, weapon options, or separate release dates for any models not yet available individually.
Possible Standalone Products
- New Space Marine infantry units
- New Ork infantry or mounted units
- Characters originally exclusive to Armageddon
- Vehicle kits associated with the launch armies
- Combat Patrol or starter-force repackaging
- New terrain from the launch setting
Why Standalone Releases Matter
Players who collect only one faction may not want the complete two-army launch box. Individual releases allow them to add the exact unit they need without purchasing unwanted models.
Separate multipart kits may also include additional heads, weapons, poses, and assembly options that were not present in launch-set versions.
Prediction confidence: High.
Prediction 4: More Space Marine Reinforcements
Space Marines are unlikely to disappear from the release calendar after the edition launch. Their enormous player base and broad range make continued support one of the safer NOVA predictions.
What Could Be Revealed?
- A multipart version of a launch-set unit
- A new character
- A Chapter-specific miniature
- A replacement for an older vehicle or infantry kit
- A new Combat Patrol
- A themed battleforce
Chapter-Specific Possibilities
A major Chapter release would be more speculative. Games Workshop could use NOVA to preview a Chapter supplement, named character, or dedicated unit, but there is currently not enough confirmed information to identify one Chapter with confidence.
The most realistic expectation is a smaller Space Marine continuation rather than another launch-sized wave immediately after Armageddon.
Prediction confidence: High for additional Space Marine products; moderate for a Chapter-specific range.
Prediction 5: The Rest of the Ork Release Wave
The Big Summer Preview confirmed a new Ork Codex and additional Ork miniatures. NOVA may provide the complete picture by revealing remaining kits, Detachment details, or army-box contents.
What Ork Players Could See
- Additional characters
- New or updated infantry
- Speed Freeks support
- Battlewagon or transport-related releases
- Armageddon-themed units
- A new Combat Patrol
- Standalone versions of boxed-set miniatures
Because the opening 11th Edition narrative focuses heavily on Armageddon, Orks are positioned to remain important beyond a single release weekend.
Prediction confidence: High.
Prediction 6: The Next Chapter of the Armageddon Story
Armageddon is more than the title of the 11th Edition launch box. It provides Games Workshop with a major narrative setting capable of supporting campaign books, missions, Detachments, characters, and future faction releases.
Possible Narrative Products
- A new campaign book
- Additional Armageddon Detachments
- Crusade rules
- Matched-play missions
- A narrative boxed set
- A new war zone or battlefield expansion
- Rules for additional factions joining the conflict
Which Factions Could Enter the War?
The story could expand beyond Space Marines, Orks, and Astra Militarum by introducing armies drawn to the conflict for strategic, religious, territorial, or opportunistic reasons.
However, predicting one exact faction would be premature until Games Workshop provides more narrative clues.
Prediction confidence: Moderate–high that Armageddon continues as a narrative theme.
Prediction 7: An Astra Militarum Follow-Up
The Astra Militarum are closely associated with Armageddon and already received new Detachments connected to mechanized infantry and heavy armour.
That creates the possibility of a supporting release, even if the faction does not receive a full new Codex immediately.
Possible Astra Militarum Reveals
- Armageddon-themed infantry
- A new officer or tank commander
- Mechanized infantry support
- A transport-focused army box
- New vehicle upgrades
- A narrative character
Why This Is Less Certain
Astra Militarum received substantial attention relatively recently through major plastic releases. Games Workshop may instead use Armageddon rules to support existing Guard collections without immediately producing another large model wave.
Prediction confidence: Moderate.
Prediction 8: One Major Faction Refresh
NOVA previews often become most memorable when they reveal an army receiving several new kits at once. A faction refresh could include replacement infantry, a new character, a centrepiece model, and a Codex or army set.
Signs of a Full Refresh
- Several silhouettes rather than one miniature
- An army set containing new models
- A redesigned core infantry kit
- Replacement of older resin or metal characters
- A new centrepiece vehicle or monster
- Updated branding across the faction
Which Factions Need Updates?
Several Warhammer 40,000 ranges still contain older sculpts or limited unit variety. However, age alone does not guarantee that an army will be next. Games Workshop also considers narrative relevance, production schedules, popularity, and how a faction fits the edition’s planned release sequence.
For that reason, predicting a refresh is more reasonable than naming one faction with certainty.
Prediction confidence: Moderate.
Prediction 9: A New Army Set or Battleforce
Army sets allow Games Workshop to introduce a Codex and new miniatures before the products receive individual releases. NOVA could reveal an army set for one of the first post-launch factions.
What an Army Set Could Contain
- A new Codex with limited-edition cover
- A new character
- One or more new units
- Existing miniatures that complement the release
- Datasheet cards
- Faction-themed accessories
Army Set vs Battleforce
An army set generally launches a new faction wave and often includes a Codex. A battleforce is usually a discounted collection of existing models and does not necessarily signal new rules or miniatures.
If the NOVA preview shows a box containing several unreleased kits, it would be one of the most important reveals of the event.
Prediction confidence: Moderate.
Prediction 10: New Detachments and Competitive Rules
The beginning of 11th Edition introduced revised Detachments and a new approach to army construction. NOVA may provide more information about how future Codexes expand those systems.
Possible Rules Reveals
- Detachment previews for the next Codex
- New Force Dispositions
- Updated army-building examples
- Additional Armageddon Detachments
- Competitive mission updates
- Future balance plans
Rules are less visually dramatic than new miniatures, but they may have a larger impact on what players purchase and field during the remainder of 2026.
Prediction confidence: Moderate–high.
Prediction 11: A New Kill Team Tease
Kill Team: Exodite was announced during the Big Summer Preview. Depending on its release timing, NOVA could tease the next Kill Team season, expansion, or pair of factions.
Kill Team frequently introduces units that later receive Warhammer 40,000 rules or individual releases, making its previews relevant even to players who do not regularly play the skirmish game.
Possible Kill Team Reveals
- The next boxed expansion
- A new terrain environment
- Updated rules for an existing team
- A completely new specialist unit
- A roadmap for the next season
Prediction confidence: Moderate, although it may be presented separately from the main Warhammer 40,000 segment.
Prediction 12: New Terrain or Battlefield Products
The Armageddon setting is ideal for industrial ruins, defensive positions, pipelines, bunkers, and war-torn urban terrain.
New starter products have already placed renewed attention on terrain, and NOVA could extend that theme with separately available battlefield sets.
Possible Terrain Products
- Armageddon industrial ruins
- Fortifications
- Modular buildings
- Objective markers
- A battlefield expansion
- Repackaged starter-set terrain
Terrain releases are particularly likely when Games Workshop wants to support both conventional Warhammer 40,000 and smaller narrative formats.
Prediction confidence: Moderate.
What We Do Not Expect
Warhammer 40,000 12th Edition
Eleventh Edition has only just begun. There is no reason to expect another full edition announcement at NOVA 2026.
A Complete Codex Release Schedule Through the Entire Edition
Games Workshop may reveal several upcoming books, but it is unlikely to publish the exact order and dates for every faction years in advance.
A Completely New Faction Without Earlier Teasing
A surprise is always possible, but early-edition resources are more likely to focus on existing armies, Codexes, and range updates.
Every Launch-Box Unit Released Immediately
Standalone releases are likely over time, but they may be spread across several release waves rather than appearing simultaneously.
Detailed Rules for Every Upcoming Codex
The preview may show themes and selected Detachments, but complete rules will probably remain tied to later Warhammer Community articles and product releases.
What Would Make the NOVA Preview a Success?
For Warhammer 40,000 players, a successful preview does not require dozens of surprise miniatures. It needs to provide a clear direction for the edition.
The strongest presentation would include:
- A Codex roadmap
- At least one substantial faction reveal
- Standalone plans for launch-set miniatures
- The next stage of the Armageddon narrative
- A preview of new Detachments
- Approximate release windows
This would give players enough information to plan purchases without revealing every product scheduled for the following year.
How the Predictions Affect What You Should Buy
Space Marine Players
Core infantry, transports, and flexible vehicles remain safer purchases than building an army around an unconfirmed Chapter release.
Ork Players
Waiting for the complete Codex and model wave may be sensible before purchasing several duplicate units. Existing Boyz, transports, and broadly useful units should remain strong collection foundations.
Astra Militarum Players
Chimeras, infantry, Leman Russ tanks, and other established units already work with the Armageddon Detachments. Do not delay an entire army project based only on the possibility of new themed models.
Players Starting a New Faction
A Combat Patrol or starter product is generally a safer first purchase than buying a large speculative army before its 11th Edition Codex is announced.
Collectors
Launch-box exclusives can be attractive, but many miniatures eventually receive individual or multipart releases. Buy the box when you value its complete contents rather than assuming every model will remain exclusive.
Pre-Preview Buying Tips
- Do not purchase speculative models based only on online rumours.
- Prioritize units already useful in your current army.
- Wait for the Codex roadmap before starting a large second faction.
- Remember that previewed products may not release immediately.
- Expect Canadian release dates to follow official Games Workshop schedules.
- Check whether launch-set models will receive multipart versions.
- Avoid paying inflated prices for supposedly exclusive miniatures without confirmation.
- Use preview information to plan purchases, not to abandon a collection you enjoy.
- Follow official reveal coverage for exact product details.

A Games Workshop Reveal Seminar is listed as part of the convention. The exact games, factions, and products included in the presentation have not yet been fully announced.
What is the most likely Warhammer 40K NOVA reveal?
An updated Codex roadmap is the most likely major announcement, potentially accompanied by the next Codex, new miniatures, and standalone releases from the Armageddon launch wave.
Will new Space Marines be revealed?
Additional Space Marine releases are likely during the opening period of 11th Edition, but no specific NOVA Open miniature or Chapter release is confirmed yet.
Will more Ork miniatures be shown?
Orks are a strong possibility because their new Codex and additional miniatures were already previewed for 11th Edition. NOVA may show the remaining release wave or standalone kits.
Could Astra Militarum receive new Armageddon models?
Armageddon-themed Astra Militarum models are possible, especially given the faction’s new mechanized and heavy-armour Detachments, but no specific new Guard kit has been confirmed for NOVA.
Will there be another Warhammer 40K edition announcement?
No new edition is expected. Warhammer 40,000 11th Edition has only recently launched, so the preview should focus on its Codexes, miniatures, and narrative expansions.
When will NOVA Open reveals be released?
Previewed products may release weeks or months after the event. Games Workshop normally announces exact pre-order dates closer to each product’s launch.
Where can I buy new Warhammer 40K releases in Canada?

Final Thoughts
The most realistic Warhammer 40K NOVA Open 2026 predictions are an updated Codex roadmap, the reveal of the next post-Orks faction, and more information about standalone releases from the Armageddon launch wave.
Additional Space Marine and Ork products are likely during the opening months of 11th Edition, while the ongoing Armageddon conflict creates room for new campaign rules, Detachments, terrain, and Astra Militarum support.
The largest uncertainty is whether NOVA will reveal a complete faction refresh. It is possible, but players should avoid treating any specific rumoured army as confirmed until Games Workshop shows the models.
The best approach before the preview is to continue building broadly useful units, avoid expensive speculative purchases, and use the official NOVA announcements to plan the next stage of your collection.
