the thing you need to understand is PS3 players have patience
and i think a year later more than makes up for it with:
Improved graphics
all the DLC you paid for on the disk
expected Exlusive DLC
added gameplay not seen on the 360 version
Trophies
Home support
regardless i wont be getting it, i didnt get the 360 version either even when it was £12
so your telling me a game sold on a console with a much larger install base sold more than a console with, at the time significantly less install base!??!
