And they have no plans to support modding with this game. Their reasoning being that it isn't just a CA game... I imagine Games Workshop doesn't want them to.
They have said this game will be a "trilogy" with the first races being available being: The Empire, Vampire Counts, Dwarves, and Greenskins.

Sucks that there is no modding support, but still, everything they've said so far sounds pretty badass.
Rumors on the Total War forums is that it'll release fall/winter of this year. They have been working on it for years already... I remember seeing a shot of one of the computer's showing a Warhammer model during Rome 2 development.
And now, back to my Geat viking campaign. About to be pounding on the Sassanids from the East.
