In the latest Qore episode for June (that someone happened to record HERE) a new PSP model called the PSP GO! has been confirmed, and if you listen carefully at 3:50, you can hear the guy say there is a new Metal Gear Solid game coming. Probably the same game that Kojima is teasing us about currently (most likely MGS Portable Ops 2) .
