Sony is aiming for a worldwide release by the end of 2011.
It’s got an OLED touch screen, and a touch pad on the back, a built in mic, a PSV card slot, a memory card slot (probably some Memory Stick variant), and front and rear cameras.
That leak was fairly accurate (even if some of the information it contains doesn’t appear to have been presented).
It’s an impressive little system, and unlike the 3DS, it won’t give anyone who tries to use it a splitting headache.
No word yet on whether it will be region-free, though; hope springs eternal.
