Around the time of the Tokyo Game Show, Sony held a private meeting at its offices in Tokyo's Aoyama. The purpose was to show off the PSP2.
Several sources have confirmed to Kotaku that the PSP2 does have a previously rumored touch panel on the back of the hardware. The touch panel was described as looking like a big mouse trackpad. When Sony showed the PSP2, it did not provide concrete details regarding how the trackpad will be implemented in games and instead is leaving that to the discretion of game developers.
