The Sony PSP hasn't been he quirkiest or most innovative of consoles both in terms of available software and hardware add-ons. Things are apparently about to change though, as the PSP Camera already released in Japan will soon hit the US and then most probably the world. Same thing with the GPS unit, only difference being this one will support a lovely Metal Gear Solid game. Further info should be available here and here.
