Grand Theft Auto IV, STALKER:Clear Sky (although, I'm afraid that STALKER's success in the West will move the game in the wrong direction), to some extent Simcity: Societies (it will really be hit or miss, either it will be a great game or a total disaster, with more suggesting the latter) and that's about it.
Funny, when I started the reply, I thought that there were heaps of upcoming games that I look forward to.
Well, maybe Far Cry 2 too (not Crysis). No trigens, an overhauled AI and a large open savanna to have fun in? Sounds good. Nothing has been heard about Alan Wake recently, wonder how that turned out. Also, Mafia 2 is ahead on the horizon somewhere, as is Fallout 3, although I don't hold out much hope for either.
