Actually GrizBe, I don't think he's quite as full of crap this time. I'm decent at sniffing out bad rumors and I'm not seeing too many here.
The Chaos Space Marine codex is the only 40k codex for this year. It is not going to be divided into two codexes or anything special. This is not the return 3.5 codex everyone has been wanting this is more a clean up than anything else.
I think this could absolutely be true. Please note that the rumor is that it will not
be a return to the 3.5e version.
Troops choices will be Chaos Space Marines and Cultists
All Cult Marines are Elites
No new Special Characters
I'll agree that this seems unlikely, there has to be upgrade characters and stuff like every other new book, yes?
Special Characters will unlock Cult Marines as troops (Kharn for Berserkers and so on)
Makes perfect sense, will just be irritating for those that would like say a pure Khorne army that isn't led by Kharn, though I suppose that's no different than any other themed army these days.
Typhus makes Cultists into Zombies
Seems likely, remember that during the Eye of Terror campaign the Lost and the Damned had rules for Plague Zombies. Fluff-wise the Plague Zombies are a creation of Typhus/Nurgle, as the Terminus Est was sighted numerous times before and during the Plague Zombie outbreaks at the onset of the 13th Crusade. Rules-wise this could easily be represented by giving the Cultists Slow and Purposeful and Feel No Pain just as an example. It'd encourage people to buy zombie kits from the Fantasy range too, which is only a good thing in GW's eyes.
Chaos Dreadnaught is removed and replaced with a new unit (like how pariahs were replaced with Lychguard)
This seems plausible too. He's not talking about literally removing the unit and rendering it unusable, see the example of Pariahs and Lychguard. It's still entirely possible to field your Pariahs as Lychguard in the current Codex and it'll be equally possible to do this with the Dreadnought model. Fluff-wise they may make it that this walker thingy is a Daemon Engine or sometimes even a Chaos Dreadnought so mutated by the warp... yadda yadda. You get it. Insert fluff wand waving here.
CSM now get a Flyer a Mechanical Chaos Dragon (model is done will be part of initial release)
This doesn't seem all that unlikely to me - though I'd be surprise if it was literally in the form of a dragon, I can definitely see Chaos armies getting a flyer broadly similar to the Stormraven or Valkyrie called
the dragon, and possibly even with a mouth and claws and stuff like most Chaos things have.
Lesser and Greater Demons are gone
Sickeningly I can't discount the possibility of this. Since Daemons are a separate force now with their own Codex it's possible we'll see the writers making the two entirely distinct on the tabletop outside of Apocalypse and similar.
Spawn replaced by “Fell Beast”
Isn't the Fell Beast that thing the Ring Wraiths ride around on in the Lord of the Rings? Anyway, I can see this happening just as the Pariahs and Lychguard did, similar to how the Dreadnought will work. Say that it's some big Chaos monster, some of which are Chaos Spawn, others mutated animals/xeno creatures, still others created in labs by Fabius Bile or something like that.
Rules for Traitor Guard are in!
This seems the least likely of all the rumors to me. Can I see Cultists being given an option to exchange laspistols for lasguns and take special/heavy weapons? Absolutely. A Chimera transport? Maybe, probably not. The addition of Sentinels and Leman Russ Battle tanks and so on? Definitely not. So yeah, Traitor Guard may make an appearance in the form of options for a Cultist unit, but nothing more.
They only did that as it was beneficial to them to. Straight afterwards they went back to kicking each others asses.
I quote "The Silent King reluctantly joined forces with the Blood Angels to defeat a Tyranid Splinter fleet."
Nothing pally about it, just a truce of conveiniance.
Actually, they didn't go back to fighting afterward, hence all the screaming and gnashing of teeth by people that are physically incapable of thinking outside of the box.
