Today Konami revealed that Metal Gear Solid: Peace Walker will arrive on the PSP later than expected. Fortunately it's not a very large delay.

The new North American release date is June 8th. The game was previously slated for May 25th. There's no mention of the European or Japanese dates - May 28th and April 29th, respectively.

A demo for Peace Walker has been available through PSN since December. It includes four missions from the full game.
