IMO:
1.)Second Analog Stick
2.)Better Screen, meaning no dead pixles at all.
3.)The ability to run homebrew without exploits (on any firmware).
4.)A different naming system with the Mp4s, or even DivX/XviD support right out of the box.
5.)More official downloadable content.
6.)Cheaper storage options (Memorystick Duos are extremely overpriced)
Thats all I can think of for now.
