The one I'm looking forward the most is Red Orchestra: Heroes of Stalingrad.
Call of Duty - Modern Wafare 2 looks very interesting, but I'm not sure I'm actually looking forward to it, CoD is too arcadey for my tastes.

Basically that's it, I don't play that much any more, and the games I play are the ones that I've been playing for 2-3 years already - Red Orchestra, Day of Defeat: Source, Day of Defeat 1.3, Medieval Total War...

Oh, and Empire:Total War, haven't bought it yet.
