I hope Sony releases a PSP without UMD drive, because it means they will have to bring the entire PSP library online.
I hope the next PSP released will be a 'next-gen' model (DS->DSi), and not just a new PSP. This way, it should still be able to play all the PSP games, but at the same time, I wont be buying a PSP just before the PSP2 is released...
