@ ohio_wookie -
1)Microsoft DOES own Live marketplace - though like all good ideas i'm sure sony will put some junk version of it's own out
2)how can you say that the 360 ISN'T next gen technology, are you serious? the 360 and the PS3 are nearly identical in theoretical throughtput of memory bandwidth and cpu processing power...you will NEVER see a difference in the best 360 game and the best PS3 game
3)can you really think of that many xbox games that you can't play on the 360 that people want to play on it? NO....they have done a pretty good job releasing patches for the most popular games out there, and the patches work flawlessly, the only exception was Forza and they relesased a new patch reasonably quick
4)the amount of information that can be puit on a BR disc means SQUAT for games as games still don't even fill up and dvd9 disc yet, and even when they do we will just use 2-3 dvd's, the size of the world in games like Oblivion isn't what takes up that much space on a disc....it's the pre-recorded AUDIO and the one part you got right..the A.I. coding,
high density next gen discs are really meant for the hd Resolutions and the hd-Audio of High def Movies
