PS3 is L.A. Noire's Lead Console

L.A. Noire- On May 17, L.A. Noire(Rockstar Games, 2011) will be released on the Playstation 3 and the Xbox 360. Although Rockstar Games seems to like PS3 a little better than the Xbox 360. Agent(Rockstar Games, TBA)will be released as a Playstation Exclusive because of the great sales made by PS3 Gamers.
So for a reward, Rockstar Games is giving Playstation an exclusive case.
Plus, since Playstation 3 stores their primary storage on Blu-Ray Discs, they get only a single disc. Xbox 360 will get 3 discs for L.A. Noire, 'cause L.A. Noire will be a big game, with over 400 cast members in MotionScan, and Xbox stores their primary storage on DVDs.
L.A. Noire is pretty much a PS3-exclusive. PS3 is their lead console.
