I imagine that the next Chaos codex will be a significant re-write in the same way as the new Marine book.
It's hard to say what will be the most viable. Simple strats can change the worth of a unit.
Fingers crossed. I think it will probably be more in line with the Necron book. Codex Space Marines have a lot of Core keywords, but I honestly think a lot of our stuff won't get the benefits of Core - most vehicles except Helbrutes, Daemon Engines, Cult of Destruction, maybe even just anything with the Daemon keyword.
I keep on wondering if GW is going to release Death Guard, then Thousand Sons, then maybe WE or EC as a separate codex, and then only update Chaos Space Marines after that. Would be a way to push new models and a new codex when CSM players are waiting and maybe by that time getting impatient.
It might also be nice to NOT be one of the earliest codices in a given edition either. Waiting is no fun, especially since they didn't give CSM two wounds in the FAQ, but neither is getting a codex, then having deal with the codex creep of everything that comes after. Being released in the first 6 months of an edition is just as bad as being the last codex in an edition. It might be nice to be a middle range release for a change. I am certainly tired of Chaos marines getting a ton of really cool stuff right at the end of an edition (Traitor Legions, Psychic Awakening) and then pretty much having to shelve a $50 book (or three in the case of PA) after getting 3-6 months of playtime with it. At least for the moment it looks like everyone who isn't Necrons or Loyalist Space Marines (who are getting theirs today, or supplements in the next three months) get to keep using Psychic Awakening stuff with errata until their new codex comes out.
As for Core, pretty much everything on foot that isn't a character will get it. The exclusions I would bet on are Daemons (since you can't include them in your main detachments without losing your legion traits), Daemon Engines, and vehicles. Helbrutes will probably be core, just like loyalist Dreads. I certainly hope cultists are core. I think the Possessed, Cult of Destruction, etc. are going to be Core.
Granted, and on topic, I actually have about 1 squad of actually painted cultists and haven't used them much. Most of my finished and pained chaos models are Astartes. I also haven't been playing much in the last couple of years, just collecting & painting. It's going to depend a bit on what things look like when I do starting playing again. I have a bunch of Escher models I planned on using a cultists that I haven't finished putting together or painting, the full line of the Servants of the Abyss which I was planning to put together as their own detachment...which I am not sure how that is going to work in this edition. I would like to see the first renegade guard models released in...forever...get some use rather than just falling into "collectors dust." I suppose they can be run as regular cultists, as there really isn't a functional difference between and autogun and a lasgun rules wise...but the renegade commissar with the powerfist & his ogryn buddy would end up joining the other renegade commissar as a technically not legal model due to WYSIWYG.
