@Selnor: "Then theres the 2nd to utilize EDRam this year. Reach boasts 720p, 30 FPS and 4xMSAA on entire image. But more impressively is what that free chip allows the devs to add to the rest of the game, 60+AI + Vehicles + flying = most impressive fights in an FPS on consoles."

Where did you get that info from? Halo Reach runs at 1152x720 instead of 1152x640, which is the case for Halo 3. It's better but not 1280x720 which everyone will think when you say 720p.
Reach doesn't even have Anti-aliasing at all. They have improved post-processing so the jaggies are less noticeable, but still no "4xMSAA on entire image".

It's 720p the same way the GT5 is 1080p. No-one cares it's not "true" 720p
