A few days ago, in an interview, Xbox chief Don Mattrick made a confounding proclamation. The proclamation said something along the lines of "GTA IV multiplayer will be Xbox360 exclusive" (please see source link for full version). After several raised eyebrows, Microsoft clarified that this was just a slip of tongue. Instead of Grand Theft Auto IV only having a multiplayer mode in the Xbox360 version, there will instead be some exclusive content only available to Xbox360 gamers. Rockstar took this one step further, and confirmed that Sony has a little something up their sleeve for PS3 gamers as well.
