GPS for PSP finally goes on sale

We've rumored, ogled, and previewed, but it's time to get official, folks. The GPS Receiver for the PSP launches Thursday in Japan, for the low price of $60, at least according to Play-Asia.com. No word on how much it'll cost you if you buy it direct from the source, although our previous post suggests a ¥5,000 ($43) price point. PSP News reports that it'll work nicely with a few titles, including "Minna no Golf-jou," "Metal Gear Solid: Portable Ops," "Planetarium Creator Ohira Takayuki Kanshuu: Home Star Portable," and "Navigation Soft." How did we ever navigate the world without this GPS antenna perched atop our PSP before?
