Xbox 360 Not Hi-Def Enough?

One of the features touted for Xbox 360 is its requirement for games to be 720p and 1080i HDTV resolutions, dubbed The HD Era by Microsoft. Today it's revealed and discussed in the official forum of Bizarre Creations, the Project Gotham Racing 3 developer, that in the final review build for PGR3 the in-game races are actually rendered in 1024x600 to get constant 30fps/2xAA. The game is stretched to 720p (1280x720) in the upscaler, which is faking HD at best." As always with late-night forum mutterings, imbibe with a grain of salt.
