Well how this person said it is perfect…so here it is.

"On its online instruction manuals, Sony Computer Entertainment has a few images for use as labels. There's one for the original PSP-1000 series (click here), and another for the current PSP-2000 series (click here). However, curiously there's also a placeholder image for the logical next-step: the PSP-3000 series (click here).

The availability of the PSP-3000 image on the PlayStation site shouldn't come as a signal that a redesign is impending — it's clear that Sony plans on revising the hardware through its supposed ten year life cycle. However, it does seem to display a bit too much forethought from the web designers that created and uploaded this image. How long will it take before we hear rumblings of yet another PSP redesign?"

So maybe a PSP Super Slim? This will bring out a lot of speculation to the PSP scene. The most "logical" thing I can think of is a PSP Phone.
