If you can't wait to get your hands on the redesigned PSP, than perhaps the inside look at the system, and it's manual over at Ookm will interest you. The blog post does a good job of not just showing what the new PSP version has for specs, but also what the original was equipped with (in case you forgot).
It's certainly interesting to see diagrams of how the new PSP will hook up to your TV, and where exactly those component cables will plug into. The post also shows off parts of the manual that explain the USB charging feature, the expanded main memory, how it will use a new remote, and exactly where the WLAN switch was moved to. It's all great info, but as a PSP fan it's always difficult to see a PSP ripped open.
