PSP owners will share in the joy of owning the new GPS add-on. I believe its primary purpose is to be used with games such as Metal Gear Solid: Portable Ops, and other future titles. Its secondary use will be for directions. The GPS receiver attaches to the USP port located in the top middle of the PSP. The antenna can be folded over and down, making the PSP less bulk during transport. The price and release date is still unavailable.
