As the whole concept of ships even bigger than Star Wars one with cathedrals strapped on their hulls that fight space demons and space orks and space elves (presumably space-DLC zergs and space -DLC undead...) is quite awesome, I'm very eager for this game.
The fantasy Warhammer Total War looks very promising too (finally a game into which ''make an army of melee units charging ahead screaming incoherently'' will work for the PC !)
As a old time 40k fan i'm kind of hyped for this, i just hope the game wont suck as all the other 40k games have done so far. (No hate for dawn of war 1 tho)
