I'm still waiting for the PSP 3000 to be hacked. Because it's modded, there's no need to use UMD's. They're kinda loud, and offer loading times. This new PSP does sound neat, but of course, I'll wait until hackers find a way to mod it first. And if hacking it yourself is safe and easy to do.
The PSP graphics have lately shown its downside. Textures are good, but models can show off their sharp pointy sides that lets you tell the difference between console and handheld. If the specs were mentioned in that video or on Wikipedia, I would have to check again, hoping that it has greatly improved. Memory storage too, for games. Comparing games like Marvel Ultimate Alliance, you can tell how the PSP version has the same levels, models, and moves, but there's no actual voice sounds for text-reading.
