Despite Sony’s financial woes over the last couple quarters, the PSP did just pass over 50 million units sold.  That being said, I must admit that this mock up pic looks pretty fatty.  The PSP 4000 is it’s new name and it could feature a sliding screen.  The PSP 4000 will also not be using UMD’s this time around and might be looking towards downloadable games.  That would surely have an impact on the environment via packaging and with retailers, as there would be no package at all.  Anyway, while this mock up looks aesthetically ballsy, will it be ergonomic?
