During its E3 2007 press conference in Culver City, Sony Computer Entertainment America confirmed that Kojima Productions' anticipated sequel Metal Gear Solid 4: Guns of the Patriots is indeed a PlayStation 3 exclusive. It will release simultaneously worldwide in early 2008.

Today's news lays rest to ongoing rumors that the game will be brought to Xbox 360; most recently, Konami's CEO strongly hinted at a potential multiplatform strategy for the game.

Metal Gear creator Hideo Kojima came to the stage to show a new real-time trailer running on PlayStation 3 and speak on the game. "The story for Snake will end, and also, for me as a game creator, this will be my last involvement in the series," said Kojima. He noted that all of the series' plotlines and mysteries will be resolved. Gameplay remains stealth-based, but is set within battlefields this time around. Kojima promised to pour his 20 years of experience on the series into MGS4.
