Force feedback, motion control
Force feedback via rumble is something that's easy to overlook, but many people realised it was missing when the Sixaxis arrived weighing less than a feather. Having a rumble that matches in-game actions makes you feel more connected, and its inclusion in the PSP 2 can only be a good thing. Something else that seemed like a bit of a gimmick until the Wii and iPhone came along is motion sensing. Some form of tilt mechanic that works like the iPhone but in a more advanced way would allow for a greater variety of games and some really interesting game mechanics.

OLED screen
There's no denying that the current PSP screen is great. It's large, colourful and, on its release was quite spectacular to look at. We want it to be better though. We reckon you could get a screen with at least twice the native resolution of the PSP even if the size remained the same. OLED technology would be our choice for the display, as it would produce far better blacks (an area in which OLED has the clear advantage over LCD) and it uses less power. We all know how short the PSP's battery life is, so anything that helps gamers eek more play time from a single charge is a bonus. The PSP screen's one disappointment, ghosting, would obviously also be a thing of the past, giving a much better quality of image overall. You could argue that a higher resolution display isn't needed on such a small screen, but we're convinced the PSP 2 will offer a sharper image.

Foldable design
Another advantage of OLED technology is that it's flexible. This would allow the PSP 2 to be a sideways folding clamshell design, effectively making it small enough to fit in your pocket (and protect the screen at the same time). Considering the slight size increase over the original PSP that will be needed in order to include an extra analogue stick, the clamshell design would make the machine smaller than the original when not in use. This might sound like Minority Report stuff, but when the PSP was released it blew us all away with the tech that had been crammed into such a small device. We expect the PSP 2 to be on the same bleeding edge of technology.
