as an ex 40k player, have to say those banshees are great :)
Yeah, Space marines, orks and eldar are the confirmed races in Dawn of War 2 so far. Soooo I'm guessing the 4th race will be chaos ;)
The game will also use Games for Windows Live, allowing it to be tied to your xboxlive gamertag (as the game will be released on the xbox360 too). Fortunately you will be able to use the Games for Windows Service for free (it wont require an xboxlive sub to play online like Gears of War on the PC).
Apparently also the game will do away with base building (or at least I read it would do away with it). Will see as more previews of it appear on thar intarweb.
Actually no, I'm wrong
4th race will be......................................................
TYRANIDS!
