The Next Generation Portable, NGP, PSP2--whatever you want to call it--features a massive 5-inch OLED touch screen, a rear touch pad, two analog sticks, and two cameras.
L and R shoulder buttons flank the device up top. Noticeably absent: a UMD drive.
The rear of the NGP features a touch-sensitive pad that players can use to control games. We're imagining even more functionality for the area that could come into play as well.
The NGP also has stereo speakers, a built-in microphone, and all of the game buttons from the original PSP.
Here is a still-frame demonstration of how the rear touch pad might be used.
Here we see what's likely to be the NGP's home screen, allowing the user to clearly see and access all of the device's features.
From this angle, we can see the two analog sticks protruding out more than the PSP's "nub" did.
