L.A. Noire not a PS3 Exclusive

L.A. Noire was supposed to be a Playstation 3 exclusive, but according to Gameinformer that is not the case now. On a issue of their recent magazine, they made a mistake of letting out that the game is coming to the Xbox 360, this was probably supposed to be released at the upcoming "X10" Press Conference or at E3.
Quote by Matthew Kato, Gameinformer Staff:
If you haven't heard much details about the game, the game takes place in the 40's and is going to be Published by Rockstar Games. The games currently in development by Team Bondi and looks to be a great title.
