Ok, since there seems to be confusion about what the launch titles actually are...
CONFIRMED BY MICROSOFT- Project Gotham Racing 3 (although there are still rumors it won't make it, guess we'll see), Perfect Dark Zero, Kameo, Need For Speed Most Wanted, Madden 06, NBA Live 06, Tiger Woods PGA Tour 06, FIFA 06
CONFIRMED BY THE COMPANIES RELEASING THEM- Gun, Quake IV, NHL 2k6, NBA 2k6, Top Spin 2, Call of Duty 2, Amped 3, Tony Hawk's American Wasteland, Condemned: Criminal Origins
Now, according to the respective companies those will be out on day one, but since Elder Scrolls IV was on that same list, as is now not coming out until next year, take all except the first 8 with a grain of salt. Several are missing that most likely WILL be out as well (DOA 4, Ridge Racer 6, etc.). The only ones of those I think may not make it out day 1 are Top Spin 2, Amped 3, and maybe PGR3. Those are just guesses though. As for what I'm getting... Quake 4 is preordered, and has been for almost 2 months. Considering several others as well (Gun, Kameo, Condemned), but I won't really choose until the day, most likely. Although if the box version of gun gets a good review, I will probably preorder that as well.
