The GPS add on for the Sony PSP has been released, it looks nice and small, iot plugs into the top of the device, and looks to fold onto the back (not too sure of that). There are no mapping solutions available yet, but apparently there are a couple games that take advantage of the GPS functions, "Minna no Golf-jou," "Metal Gear Solid: Portable Ops," and "Planetarium Creator Ohira Takayuki Kanshuu: Home Star Portable. There are no details on exactly how the GPS interacts with the games, but it sure opens up a whole new aspect to gaming.
