Every game except for Tony Hawk's Whatever and most (if not all) of the sports games.
So:
Kameo, Gears of War, PD0, Halo 3 (didn't you hear, EBGames has it on their site?

), DoA4, Quake 4, Gears of War, CoD2, Condemned, Prey, Gears of War, ES4: Oblivion, Saints Row, Gears of War, Full Auto, PGR3, Gears of War, NFS HP2, Gears of War, some more that I can't remember, and Gears of War.
I'll probably end up spending about $1000 on video games by the end of the year.
And yes, I know that some of the above are not launch titles. Until an official final list is available, that's what I'm going with.
Edit: Forgot Kameo and Gears of War. **slaps forehead with tire iron**
