a PSP redesign like the one at the top of the thread would be great. Just get rid of the 2nd smaller screen and all that extra plastic around the big screen so that you basically have a widescreen GBA SP. If there's gonna be a 2nd screen, it should be a small one on the outside of the clamshell (like many cell phones) and it should be a touch screen for easier mp3 control. Make the UMD drive slot loading and place it in the area where the buttons are. Then just make it stylish as Sony knows how to do, and I think they'd have a winner. I'm pretty sure I'd buy it because one of my biggest beefs with the current model is that the thing fits in your pocket, but not as comfortably as i'd like.
My Top 5:
Shadow of the Colossus, Metal Gear Solid 3, Shenmue, Skies of Arcadia, Chrono Trigger
My 2 nex-gen systems: PS3 
and Wii 
Prediction Aug '08: We see the PSP2 released fall '09. Graphically, it's basically the same as the current system. UMD drive ditched and replaced by 4-8gb on board flash memory. Other upgrades: 2nd analog nub, touchscreen, blutooth, motion sensor. Design: Flip-style or slider. Size: Think Iphone. Cost: $199. Will be profitable on day 1.
