Rock you have no clue. 360 was launched as HD console. It was never upgraded. There was a Patch that was sent out to do 1080p. But it was always able to do 720p. Also Dogweed, So far there is no evidence of your claim in any games. And if we needed 2 discs towards the end of 360's life for alot of games BIG DEAL. MS are very good at compression though.
