Japan is certainly excited for the new GPS peripheral. amazon.co.jp is reporting that its first shipment for the device is already sold out. The customers that are buying the tool are also buying Metal Gear Solid: Portable Ops, most likely because the Kojima stealth game happens to support the device. They're also picking up Chotto Shot (the PSP camera), because as you know, once you start buying peripherals for a system, you want to buy them all. The hardcore Japanese PSP fans appreciate the PSP's Swiss Army knife-like functionality... how about you? Will you be picking up the GPS system when it comes out?
