Speaking during a Konami on-stage presentation at Tokyo Game Show 2010, Hideo Kojima announced a 2011 debut for the Nintendo 3DS version of Metal Gear Solid 3: Snake Eater. In a surprising move, the game's original title won't be spruced up to match its enhanced visuals and new platform. (We made a page for Metal Gear Solid Double 3 + D: Stereoscopic Synthesis Subsequence and everything!)
Kojima Productions will reveal more details about the project at a later date. For now, it seems to be a faithful update and port of the PlayStation 2's snake-attack classic.
