Kojima Production's Ryan Payton has assured PS3 gamers that MGS4 will not be compromised by cross platform development.

Speaking during a Kojima Production podcast, Payton said: "I can tell you honestly at this point, we have not changed the game in any form with the idea of 'oh, we got to do this on 360.' Put aside whether or not we're developing for 360 or not, the game is built on the PS3 hardware."

Metal Gear Solid 4 is currently a PlayStation 3 exclusive, although there have been persistent rumours that the title will go multiplatform and also release on Xbox 360.

Current retailer estimates place the game for release in March 2008.
