1. Dual Joysticks
2. Louder, its impossible to hear (even with headphones) on an airplane
3. Anti-Piracy shit. I don't know how, just solve the piracy problem.
4. More PS3 games going to PSP. Examples - LBP portable, GT5 portable, Resistance portable
5. Some kind of tilt function like the iTouch/iPhone has. That would be cool. I guess its sorta like Sixaxis like was said in the original post
Edit: 6. Extended Batterly Life. The current battery is a joke
