According to the November 2007 issue # 76 of the Official Xbox Magazine Sony has secured the next Grand Theft Auto, which would be number 7 in the series, to be a true exclusive to the Playstation 3.
"Rockstar really wanted to make a game that you can truly only do on PS3, harnessing the power of the Cell and Blu-ray disc and this deal lets them do just that" as said by Sony's Michael Shorrock in a statement to the press. " 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!"
Looks like the Xbox fans may be out of luck when it come to the next installment of Grand Theft Auto. If they do release a 360 version it sounds like it would have to be on multiple dvd discs if the game truly takes advantage of Blu-ray.
One thing is for sure. This will be interesting to watch play out. Stay tuned!
