Speaking with The New York Times, Sony Computer Entertainment boss Kaz Hirai alluded to a list of potential features for the successor to the PlayStation Portable.

He suggested the new device may include both touch-screen functionality and traditional buttons, allowing for depth in the catalogue of games developed for the possible platform.

“The games being played on Android and Apple platforms are fundamentally different from the world of immersive games that Sony Computer Entertainment, and PlayStation, aims for,” Hirai told The Times. “Depending on the game, there are ones where you can play perfectly well with a touch panel but you can definitely play immersive games better with physical buttons and pads. I think there could be games where you’re able to use both in combination.”

Hirai also suggested that the PSP2 would be unlikely to include any smart phone features as “he did not want to confuse game fans over which device to buy,” reports The Times.
