I believe sorcerers were going to be added, i read somewhere on one of the news articles that "Beware of perils of the warp when casting powers" was a hint to psykers being added. Lets hope that's trues! WITNESS YOUR DOOOOOOOM! - Some psyker from dawn of war ( i think that's what he said anyways)

Of course there must be iconic classes like Berzerker or Plague Marine, but what about Obliterators, Possessed Marines and others? They need some love, too.

9 copies, 9 it's the sacred number of Tzeentch

XD

Tzeentch is always lurking.

On topic - I want to see proper raptors. With arched jumppacks.
And properly talon'd feet.

I'd like to see Chaos Terminators as one of the classes.

Any melee class with a Khorne blessing would most likely be my choice.

Raptors! Raptors everywhere! =D

It'll be interesting to see how they'll mix ranged combat vs melee.
I also really hope there will be sorcerers. Bolt pistol and sword is just bad ass. And then you throw a lightning bolt. Doesn't get any better really.
