Games Workshop maps Horus Heresy releases for summer 2026

The Big Summer Warhammer Preview Show 2026 is set for 7pm BST on Friday 26 June 2026, with Horus Heresy already lined up behind Saturnine and a summer schedule of new miniatures, rules support and campaign material.

What the summer 2026 roadmap is really saying

The updated summer 2026 Horus Heresy release schedule highlights new battle groups, plastic tanks and campaign books. The line is getting more than one-off character kits or a pure rules refresh. It is a release pattern that helps both new armies and existing collections grow around core infantry, armoured support and narrative play.

Games Workshop’s official article “The future of the Horus Heresy - Digital downloads, expansions and new miniatures” lays out digital downloads, expansions and new miniatures alongside boxed releases. The line is being supported through multiple channels at once, not just boxed releases.

Buy now if your project needs a core, wait if you are chasing the next expansion

The clearest buy-now signal is for players who need to finish a playable core force. New battle groups matter most to anyone starting a legion army from scratch, because those boxes anchor a force faster than piecing units together one kit at a time. If your collection already has the infantry you want, plastic tanks and campaign books point the next spend toward support units and narrative add-ons rather than rushing into every current bundle.

The wait-and-see case is strongest if you are building around a very specific legion flavour or a niche armour-heavy concept. A roadmap built around expansions and new miniatures means more options are coming, and it can be worth holding some budget back until the next preview cycle sharpens the picture. That is especially true when the line is being positioned around larger seasonal reveals rather than isolated drops.

Saturnine is the clearest sign of where GW is placing its weight

The biggest current marker is Saturnine, the new edition of Horus Heresy. Warhammer Community published the FAQ “Saturnine: Your questions on the new edition of Horus Heresy answered” and “Saturday Pre-orders - Saturnine.” Those pieces put the edition at the center of the line’s next phase.

For collectors, Saturnine is a strong reason to hold off on any major rules-based purchases until you know how the new edition is shaping up. For hobbyists who want to paint and build rather than chase the tightest competitive edge, it is still a good moment to commit to a project because the edition is already being supported with official questions-and-answers and a pre-order cycle.

The preview show is the pressure point for the rest of the summer

Seasonal preview shows are where the company tends to line up the next wave of attention, and Horus Heresy is part of that wider reveal pattern.

If you are planning hobby spending, the preview window is the moment to watch before you lock in a large order. The presence of a dedicated Horus Heresy hub, plus official downloads, setting information and news updates, means the line is being fed with ongoing support rather than waiting for a single boxed launch to carry it. The preview show is the checkpoint before deciding whether to buy now or wait for the next expansion announcement.

What this means for legion collectors and 30k armies

The practical read is simple. If your army still needs a battle-group-style foundation, summer 2026 is a good moment to move. If you are already deep into a force and care more about which tanks, campaign books or upgrade paths fit your legion identity, the roadmap argues for patience until the next round of reveals lands.

Games Workshop is supporting 30k with rules, digital downloads, expansions and new miniatures while continuing to build out the setting as an active product line.
