Throughout gaming history, we have seen the importance of exclusives. Sony themselves are no strangers to exclusive titles. They were the bread and butter of the company while the PS2 was around.
Sony wouldn’t want to rest on their laurels. Microsoft have really stepped it up in this generation, throwing money around at anyone who will take it, and it is paying off too. The 360 is still outselling the PS3, even though the PS3 has some really killer hardware like a BD-ROM in it.
