New rumors say 40k’s Chaos Space Marines are getting new models, box sets, and updates for World Eaters, Thousand Sons, and Death Guard!

Chaos Space Marines are gearing up for something big, and the latest rumors have players bracing for an avalanche of new models and box sets. If you’ve been waiting for fresh reinforcements, it looks like Games Workshop has heard the call.

With all these changes on the horizon, now’s the time to start planning. Which army is coming out on top? What’s inside these rumored new releases and boxes? Let’s break it all down.

Each major Chaos faction is rumored to be getting new releases (as Emperor’s Children already has theirs), with Thousand Sons, Death Guard, World Eaters, and Chaos Knights all in line for updates. Some armies are scoring brand-new units, while others might be stuck with minor additions.

Chaos Space Marines: New Rumors

Thousand Sons: New Toys, No Tzaangors (Finally!)

A brand-new set of automated robots decked out in the unmistakable blue-and-gold of the XVth Legion. These aren’t just repackaged units with a different datasheet—these are entirely new models built to fit the faction’s arcane, high-tech aesthetic.

Along with these cyborg warriors, it looks like the box will also include some classic favorites: Sorcerers, Rubric Marines, and Terminators. What’s missing? Tzaangors. That’s right, not a single beaked beastman to be found. After years of them being shoved into every Thousand Sons release, this is a change plenty of players will be happy about.

This shift suggests a stronger focus on the Legion’s core identity: psychic mastery, automaton warriors, and elite infantry. Whether these robots function like Castellax battle-automata from the Horus Heresy or something completely new, they’re bound to shake things up for Thousand Sons players.

Death Guard: One New Model—And That’s It?

Death Guard fans might not be as lucky. A new model accidentally sent out by Games Workshop spoiled one of the upcoming releases, and right now, it looks like that might be all they’re getting. There’s talk of a new combat patrol and a larger box set, but details are scarce.

If this is truly the only addition to the army, it could be a tough pill to swallow. Compared to the changes happening for other Chaos factions, Death Guard seem to be stuck in place. The current range is solid, but it might not change much this time around. Some new units beyond the single leaked model would do wonders to keep the army fresh.

World Eaters: Smaller Combat Patrol, Same Brutality

Current rumors suggest it’ll include 22 models—most of them melee-focused, as expected. A squad of 10 Jackals, a squad of 10 Khorne Berserkers, a Daemon Prince, and a Master of Executions are expected to be in the box.

While it’s not a groundbreaking release, it does provide an easy way for new players to jump into the army. The real question is whether this means World Eaters will get additional new units later. With AdeptiCon on the horizon, it wouldn’t be surprising to see a surprise reveal or two. If nothing new gets announced, players might be stuck hoping for a second wave down the line.

Chaos Knights: A New Big Guy Enters the Fray

The new release is rumored to come in a larger box alongside War Dogs and a codex, making it a solid starting point for anyone looking to field an army of corrupted war machines. For players who already run Chaos Knights, this could be a good excuse to add a new centerpiece to their collection.

Final Thoughts

The Chaos factions are all getting some attention, but not everyone is walking away with the same level of support. Thousand Sons appear to be the biggest winners, with their new robot units giving them something unique to work with. World Eaters and Chaos Knights are getting some useful reinforcements, but Death Guard players might have to settle for scraps.

With Adepticon coming up, there’s still time for more surprises. Chaos Marines have been getting a lot of love lately, and it wouldn’t be shocking to see another reveal that wasn’t part of the current rumor mill. Until then, we’ll just have to wait and see just how accurate these leaks and rumors turn out to be.
