More PSP

While PSP sales have been struggling against the DS it's surely to early to talk of binning the format. Isn't it? Of course it is. Yes, the PSP may be suffering from a lack of must-have titles and yes, the UMD movie format is dead on its arse, but the PSP is still a more than viable games/multimedia combo that, homebrew aside, hasn't quite found a killer app. This article over at Gameworld disagrees. Is it really time for Sony to give up on the PSP? Can Nintendo ever be overtaken in the handheld games market?
