I think Sony is a bit over reacting and seem a bit stubborn. What stops them from creating the next Call of Duty game? Do the studios that Sony bought make the games available for the XBox?

Better to sell games for both platforms than only one? Isn't it already normal to have exclusive games for a short period of time?
