Nikkei: PSP2 will have 3G cellular data, OLED touchscreen

We're only four days away from a supposed January 27th unveiling, but apparently there are still more juicy PSP2 rumors left to dole out -- Japan's often-reliable Nikkei newspaper reports that the handheld machine will sport a crisp OLED touchscreen and 3G data from NTT DoCoMo when it arrives later this year, with the latter enabling multiplayer action and even full video and game downloads over the Japanese cellular network. What's more, the paper confirms that the screen will be physically larger and powered by some potent new silicon. So, how will Sony differentiate this PSP2 from the PlayStation Phone and tempt you to buy both? The game system won't make calls.
