so with these installs you wont need the game, that is very diff with the sony machine because you still need the game in the console after you install, i really do think that i have misread your post because wouldn't people just get the game install it then send it back to the shop.
so have i got this correct,
Microsoft
buy game, install it to console dont need the disk anymore
Sony
buy game, install to console, still need disk in the system
