At PAX 2012, Konami and Hideo Kojima revealed that Metal Gear Solid: Ground Zeroes will be a prologue, and will release for PlayStation 3.
Konami isn't calling the game Metal Gear Solid 5, and it isn't ready to commit to any platforms. However, the game is running on a PC with specs similar to current generation consoles. Keep an eye on our website as the trailer for the game should be available online in about an hour.
According to Konami's Twitter account, the FOX Engine which is being used for Ground Zeroes, could be used to support other Konami titles like Silent Hill.
