Nice. I've always thought that exclusivity just shafts consumers - you make a choice on a platform (PS3/XBox 360) and people get paid off not to release things on other platforms (despite the fact it'd mean more sales), and you end up worse off for YOUR own personal choice.
DLC exclusivity is even lamer. "Hey, you can have the game - thanks for purchasing it - but because people gave us money we're not going to give you anything more, or the chance to provide us with any more money.".
I hope more studio's develop for both platforms without having exclusives.
