You can also see what looks to be the PS button underneath the D-Pad (with placeholder marking) and the big, rounded rectangle in the middle is reportedly a touch-sensitive strip capable of mimicking dual-analog input.
This prototype device certainly looks like the real deal, but the lack of a custom Android skin and any obvious PSP branding raises even more questions. When will this device be ready, let alone announced? How much will it be? Maybe most importantly, what kind of games will be compatible with it?
