At a recent Metal Gear Solid Peace Walker
event, Konami Q/A people asked game journalists, Gamepro
among them, if they'd mind seeing Peace Walker show up on the PS3. Specifically, as a PSN release and with online multiplayer. Granted, this wasn't completely out-of-the-ordinary for a developer question, but it raises some interesting possibilities.
Peace Walker was originally going to be called Metal Gear Solid 5, so it was a big deal from the beginning--it's an important chapter in the series, not just some interquel throwaway. Kojima has done special re-releases for every game in the series except for MGS4, so this would be a new way for him to touch up an MGS game and give it a special edition. For now this is just a Q/A inquiry at a press event, but an unusual and intriguing one.
