More big rumors are here for 40k and Horus Heresy: plastic Primarch kits for Dorn, Vulkan, and Guilliman may be on the way, something big for 11th edition.
The warp is swirling with talk of new kits, and this time the rumors aren’t just about tweaks. If these are proven true, Games Workshop is lining up a massive push into plastic models for both Horus Heresy and Warhammer 40k.
From Primarchs to Tyranids, this potential lineup looks stacked.
Let’s break down the latest on what may be on the way for Warhammer 40k, according to collaborated leaks and Valrak.
New Horus Heresy Primarch Models Going to Plastic
Updated October 23rd, 2025, by Rob Baer with the latest.
For years, Heresy players have had to wrestle with resin Primarchs, sometimes literally, when their parts warped. That era may be closing. The current word is that Angron Transfigured will be one of the last resin Primarchs, with all future characters moving to plastic.
It’s a huge shift that could make these iconic figures easier to build, more durable, and more widely available.
- Rogal Dorn: A new plastic Dorn kit is rumored again, themed for the Siege of Terra. Whispers point to two loadouts: a massive power sword or a brutal chainsword. Whether it’s a single kit or separate versions isn’t clear, but either way it’s a big moment for Imperial Fists players.
- Vulkan: Salamanders fans may finally get their Forge-Lord in plastic. With the new edition revisiting Isstvan and the Salamanders taking center stage on the box art, this rumor carries weight. No confirmation on a new pose, but even a straight material upgrade would be huge.
- Roboute Guilliman: Early rumors suggested a new Guilliman for 40k, but now these updated rumors now place him in 30k instead. A plastic version for Horus Heresy fits the current refresh strategy and would round out the loyalist line nicely.
Other Horus Heresy Plastic Refreshes
It’s not just the Primarchs. The armor and unit ranges are also getting attention:
- Cataphractii & Tartarus Terminators – A full redesign is said to be on the way, starting with Cataphractii in a larger scale, possibly closer to Indomitus Terminators. Tartarus is rumored to follow later.
- Abaddon – The Despoiler may be reimagined in this new scale, potentially tied to Siege of Terra or a Justaerin diorama.
- Justaerin Terminators – Sons of Horus elites are rumored to be returning in plastic alongside Abaddon.
- Big Tanks – With the plastic Fellblade already out, the Falchion, Glaive, and other super-heavies may be next.
Release timing? Spring next year is the supposed target, with possible previews at major events before that.
How will 10th Edition End?
Drawing from established patterns and the latest rumors, it’s becoming more evident that the galaxy is poised for a clash of titanic proportions.
Games Workshop (GW) has established a recognizable release pattern over recent years. This three-year cycle tends to see major narrative arcs unfolding across new editions, similar to how previous campaigns like Psychic Awakening and Arks of Omen unfolded in 8th and 9th editions, respectively.
With the 10th Edition currently at its effective codex end, we can probably expect more significant events before the inevitable transition to 11th Edition in 2026. Basically, every year in the three-year cycle, they release a major game or hobby product.
Emperor’s Children Happened
The first major event of 2025 is the return of the Emperor’s Children, one of the Traitor Legions led by the infamous Fulgrim, a Daemon Primarch. This mirrors how the World Eaters and their Daemon Primarch Angron were introduced towards the end of 9th Edition. The parallels are striking: a long-awaited Traitor Legion returns with a major character, setting the stage for significant conflict within the Imperium.
The question is whether the return of Fulgrim will be an event that shakes the galaxy, forcing the Imperium to respond with full force?
A New Loyalist Primarch’s Return?
Forge World Horus Heresy Primarch
If the Emperor’s Children and Fulgrim’s return does spark chaos, then the response from the Imperium could come in the form of a long-awaited loyalist Primarch. Leaks and speculation point towards the return of either Leman Russ or Rogal Dorn.
Both Primarchs have been missing for millennia, but recent hints in the lore have suggested that their return could be imminent.
Russ, the Primarch of the Space Wolves (here are the rumors for his return), famously left the Imperium, claiming he would return during the galaxy’s darkest hour. Rogal Dorn, known for his staunch defense of Terra, disappeared after the Horus Heresy.
His fate remains shrouded in mystery, but the return of either of these iconic figures would be a monumental event for the Imperium. The returning loyalist Primarch would likely face Fulgrim in a narrative climax, much like the showdown between Lion El’Jonson and Angron in the Arks of Omen campaign.
More Primarchs Other Than Russ on the Horizon? Maybe…
Before bringing back a heavy hitter like Leman Russ, the smart money’s on one of the “background” Primarchs making a comeback. We’re talking Vulkan, Jaghatai Khan, or Corvus Corax, all of whom have story hooks wide open for a return.
Vulkan’s a solid bet, since as a Perpetual, he literally can’t die. Khan is in the Warp somewhere, possibly still fighting the Drukhari, and if they get a big refresh, it would make sense for the Khan to come rolling back in. Corax is hunting Lorgar in the Warp, so why couldn’t he pop back up and steal the spotlight for a little?
What we have seen, though, is a shiny new Logan Grimnar model so massive it could make a Primarch jealous, and that might actually explain some of the confusion. Leakers catch a glimpse of a hulking Space Wolf with flowing hair and assume it’s Russ himself.
Not everyone clocking these things knows their lore well enough to tell the difference between the Chapter Master and the Wolf King.
On top of that, some of these so-called “Primarch leaks” might not even be for Warhammer 40k at all. There’s a good chance a few of these plastic legends belong to Horus Heresy, where Forge World’s resin heroes may slowly be getting swapped for plastic glory.
Games Workshop knows those big characters sell like hotcakes in both systems, so whether it’s a 40k reveal or a Heresy drop, it’s all the same kind of plastic crack to them.
Setting the Stage for 11th Edition?
After the rumored Primarch release (whatever it is), all signs point towards GW launching 11th Edition Warhammer 40k in the summer of 2026. This transition would follow their established pattern of moving the narrative forward with new rulesets and campaigns to accommodate the galaxy-shaking consequences of the return of these Primarchs.
Final Thoughts On Latest New 40k Primarch Rumors
The final days of 10th Edition promise to be full of dramatic confrontations, monumental character returns, and significant lore developments. The battle between loyalist and traitor Primarchs will undoubtedly reshape the future of the Warhammer 40k universe, leading directly into (or during) the next edition with more expansive lore and gameplay opportunities.
Moving Primarchs and elite units to plastic, rolling out redesigned Terminators, and refreshing beloved Xenos models like the Red Terror could inject real momentum into both games.
For hobbyists, this means easier builds, more conversions, and a fresh reason to expand those display shelves. For Games Workshop, it’s a clear push to grow Heresy into a true plastic powerhouse.
