I hope PSP2 come, but better not a mere horse-power upgrades. They need new novel / innovative concept to fight Nintendo and Apple.

PSP is sleek, but the demographic is too concentrated on poor 13-17 yo male. These demographic don't give u enough depth for profit.

P/S Despite having a PSP1000, i am much older than 17 yo.
