No, no, no this can't be true. Sony said that they don't pay for exclusivity and I believed them.
Also, yeah that comment, "We handed Rockstar a signed blank check because we were short sighted enough to let Grand Theft Auto's exclusivity get away from us. Oops!" simply does not sound like something a professional PR guy would say. Jack Tretton would say that but the quote isn't attributed to him.
BTW, where's ole Jackie boy been? I could use a laugh.
