Mhm. The Xbox 360 will have limited backwards capability. Microsoft hasn't released an official statement yet, but they've only said that it will be the "top-selling Xbox games", so expect Halo 2 to be on that list. Personally, backwards capability isn't such a big deal because the Xbox 360 is gonna have such a killer line-up that re-playing old Xbox games would only be to remember our past or something. Who needs Halo 2 when you can have Halo 3, Gears of War, Ghost Recon: Advanced Warfighter, Quake 4 or Perfect Dark Zero?
