Sony's second-generation mobile gaming console features a 5" touch OLED display (960x544, Samsung made, apparently with green PHOLED), a quad-core ARM Cortex A9 processor and a quad-core PowerVR (SGX543MP4+) GPU (Sony says that it is as powerful as a PS3), Wi-Fi, GPS, Bluetooth and 3G (AT&T, optional). Gaming controls include dual analog sticks, motion controls and a multi-touch pad on the rear side.
Basically Sony says that there are five basic concepts to the PS2: Revolutionary User Interface, Social Connectivity, Location-based Entertainment, Converging Real and Virtual (augmented) Reality. The Vita costs $249 for the Wi-Fi version and $299 for the 3G one.
