It's no secret that PSP has failed to compete with the technically inferior Nintendo DS. Fortunately, Sony is wise enough to admit its mistakes and to learn from them.
"Our biggest mistake, I would say, with PSP was we were just so happy to provide the PS2 gaming on the go, and we kind of stopped there," Sony Computer Entertainment's head of worldwide studios Shuhei Yoshida said.
"What we wanted to do with NGP was, besides the great graphics and CPU, think on what interface we could put in to make the gameplay really stand out. You know, something that you cannot even do with the PS3," he added.
And that something which can be done on the tiny NGP and not on the more powerful PlayStation 3 turned out to be the rear touch pads, dual analog sticks and camera-based augmented reality.
In the same interview Yoshida clarified that NGP will use edge smoothing and filtering techniques to upscale downloadable PSP games and that it will offer an option to map camera controls for those games to the NGP's second analog stick.
