Rumor: PSP 4000 to Feature Sliding Screen?

A “highly-trusted source” has told VG247 that a new model of PlayStation Portable is on its way, this one featuring a sliding screen.

However, this won’t be a “PSP 2,” they say, but rather a “complete aesthetic overhaul” based on the existing PSP tech. As for the above, it is not an actual image of the product, but is “not a million miles away” from the actual product.

Eurogamer rumored that the device would see a 2009 release, and VG247’s source vouched for that. Other details are being held close, except that we could see the handheld revealed at either the GDC or E3 this year.
