there are certain rumors about psp-4000 that its going to be released this year in December. but it has not been fully admitted by sony that its gonna launch in this year. (like previous models)
It has the following features:-
1.sliding feature like GO!
2.larger screen compared to previous models
3.better resolution than any other psp models

discuss here what should a psp-4000 have and about this pic and if any new information is told about the system then post here
p.s i do not own this pic

^ Probably because it's not just a larger enhanced clone. Sony are keen on implementing a digital distribution-based console, but to make it a viable case the only option is to run the UMD PSP along-side. That's why they're still making 3000s, and that's what the 4000 will be. I can't see them releasing two PSP models in one year, but according to the PSP's model history, the 3000 is due for an update, and I don't think they'll wait until next October to do it.
But it's hard to say what will happen.

Luigi why are they dipshits? They want to keep their PSPs updated, they always have, and we've seen a new PSP every year for the past 3 years. It'd make sense that they'd update the 3000 again into the 4000.

That's fair enough, from a business perspective.

A lot of people hate the idea, probably because they don't like the idea of digital distribution. I think it's pretty good. It's a way of kick-starting digital distribution and being one of the first companies to do so in such a big way, using a library and user-base that's already pretty big, without alienating current PSP owners. I mean, you consider the alternatives...What if they made a digital console that was stand-alone? It wouldn't have the games or popularity to support it from the get-go. What if they made the PSP digital-only? People would revolt, developers would stop making games. The solution is a parallel approach, with both digital and UMD consoles running the same games. The PSP lives on as usual, and the Go uses part of its fanbase, and its games, to survive as a digital console.

^ Which is why the 3000 is still being sold. Also, it's why the Go never took off in Australia.
To the rest of the world it makes sense, they have decent internet.

Hey..I saw that same pic for a picture of the PS2P....
