We've been hearing rumors about a non-game app store for the PSP since the launch of the PSP Go, and it sounds like the wheels are turning -- in an interview with CNET, Sony's Al De Leon said that while PSP content "will mostly be games, there's an opportunity to look at non-gaming applications." Sure, that's not exactly a hard confirmation, but it's certainly suggestive -- maybe we'll see something at Gamescom in August after all.
