With the recent Rumor Engine from GW, we wanted to revisit all the rumors we’ve heard about so far. Because at this point, there is basically no choice but for a codex to come out in the near future.
So, let’s start with what we heard from a source that had their other rumors confirmed. Maybe that will give these a little more credit, but as with all rumors, take them with as much salt as you need.
New Chaos Space Marines Codex Rumors
Originally posted on one of the large 40k forums, these Warhammer 40k codex rumors were taken down just before Games Workshop’s new codex roadmap post went live. Luckily it was reposted over on Imgur here.

There also seems to be a greater emphasis on updating the cultist/human line and most likely important in the faction. One of the unique things about Chaos is the presence of non-marine heretics. So it would be a unique space to expand on for the faction.

The deletion of the forum post might be someone asking it to get taken down or maybe even just the author decided to, we can’t know for sure.
Games Workshop Codex Roadmap
Also of note, the recent WHC Codex Roadmap post mentioned this about Chaos:
Eagle-eyed heretics** may note the lack of codexes for the Traitor Legions. Do not despair, as 2022 will be a bumper year for warp-based shenanigans.
This is a huge boon for chaos, as generic CSM has seemed to be on the backburner for the 9th edition. Assuming at least some of the rumors are true there’s huge potential for new additions and updates as the change to Primaris for loyalists seemed to have left Chaos in the dust.
World Eaters Codex Coming Next for Chaos

World Eaters are one of the four main single-god devoted legions; Thousand Sons for Tzeentch, Death Guard for Nurgle, Emperor’s Children for Slaanesh, and World Eaters for Khorne. We assume why Games Workshop would release World Eaters before the whole CSM book is probably because people who play any of the devoted legions will also buy the CSM codex as well as any potential new models too.
Meaning they can keep the releases flowing to the same customer base. Plus it’s easier to release more models this way, with a big-sized mini (such as a Daemon Primarch or new vehicle kit) to build hype and new limited edition Army boxes.

As by far one of the most popular legions, it makes perfect sense that World Eaters get their own codex. Unlike undivided legions like Word Bearers or Black legion, the God-devoted ones have much more unique models and lore, making them better candidates for dedicated books, and new models.
This also makes sense with the new rumors we’ve heard, meaning Emperor’s Children would come after World Eaters and Chaos Space Marines proper later on in the 9th Edition release cycle. Or, they could easily have gotten the idea messed up, maybe it’s CSM, then World Eaters, then Emperor’s children.
RUMORS: App Update Points to New Chaos Codex Soon
GW has recently put Heldrake updates in the 4ok app, which may mean a number of things including a new codex book soon!

It could very well be that they just gave the programmer the new stats and they just put it in without knowing when it should go live, or even toggled the wrong one “live” and didn’t remove the “old” nomenclature from the title.
So again, why put it into the app if a book isn’t coming soon. While this isn’t the biggest thing ever, this along with the previous rumors really seem to point to a new book sooner than later! There are more hints however, just check out these Rumor Engines!

New Chaos Hammer Time: GW Rumor Engine

This could be a 40k Chaos bit, as there are tons of rumors for the next year, and the tendrils on the backside of the hammer seem to point in that direction. The similarities to the twin-tailed comet however make an AoS release still a possibility as well.

Either way, the Chosen are sweet models and could really use an update. This hammer might point to them finally getting their own box release with their full range of weapons available to them.
