Like, $0.99 cheap.
Perhaps offering credence to a PSP Go app store rumour, PocketGamer are reporting that Sony are to release a bunch of PSP Go titles at the 1, 2 and 5 Euro price point. In fact, they are even reporting that Sony have been consciously approaching existing iPhone game developers and asking them to bring content to the PSP.
It's a smart move for Sony and something we're looking forward to. Hopefully they'll also release a free/affordable dev kit for individuals or very small business' to use and submit content.
