We found out yesterday that the PSP sequel to Metal Gear Solid 3 will hit shelves in the UK on May 28 -- following a March 18 debut in japan -- and today Konami has announced that Metal Gear Solid: Peace Walker will arrive (via cardboard box, fittingly) at US retail three days earlier on May 25. Although Kojima Productions is at work on a localized English language Peace Walker demo, the Japanese demo, released during Tokyo Game Show '09 (and later improved for release on PSN Japan) is pretty easy to pick up on -- and definitely worth playing. We've contacted Konami in hopes of confirming a digital release of the game for the same week the physical copies hit shelves, and maybe -- just maybe -- we'll get la-li-lu-le-lucky and score a special / limited edition for the States.
