Seriously, how often do you get an itch to play your original version of Halo?
i don't anticipate a huge delta b/w 360 games and 720 games. based upon those system specs, do you? i mean, we're getting to a point now where we're discussing 5% more textures b/w systems?
also, i've spent a lot of money on XBL games which are all older games/classics that yes, i do play a lot and want to in the future.
