Word on the street is that Sony will release a PSP-4000. You act surprised.

The PSP-4000 would replace the current PSP-3000; it will have nothing to do with the PSP Go, Sony’s UMD-less system that’s due on October 1.

This rumor comes by way of someone (“Super_Secret”) who leaked the plans of the PS3 Slim, and look how that turned out.

I would imagine it would include things like an improved screen, better battery life, etc. You know, the things that usually happen with this type of product revision.
