Sony to unveil UMD-less PSP with slide-out buttons at E3

1UP has a bunch of new details about the rumoured PSP2. The sources are apparently from people directly involved with the system.

• UMD is definitely out and replaced with either 8GB or 16GB flash.
• Three rumoured names include PSP Slide, PSP Flip, and PSP Go!
• The same D-pad, analogue nub, and face button configuration remains, but they now slide out from the bottom of the unit
• Expected launch is September for Japan and late October / early November for US
• 100 classic and new downloadable titles including Gran Turismo Mobile as a headliner

Sony's supposedly going official with all this during its E3 press conference in early June
