Computerandvideogames.com (CVG) is reporting that they've received word from Konami that despite the rumors, Metal Gear Solid 4: Guns of the Patriots, currently remains a PlayStation 3 exclusive;
""Konami has no plans to bring Metal Gear Solid 4 to the Xbox 360 at this time," a Konami representative told CVG, reiterating that the Hideo Kojima stealth-em-up was still "exclusive to PlayStation 3."" - CVG
Now what's interesting to note is the wording - "at this time", which implies that Konami isn't ruling out porting the game over to the Xbox 360 at some point in time. Admittedly, the full statement would also seem to imply that said port isn't currently in the works. My guess is that we'll see something along the lines of Metal Gear Solid 2, where the game debuted on the PlayStation 2 and was later ported over to the Xbox as a special edition.
