Voici une brevet de Sony qui explique en gros la connectivité entre la PSP et la futur PlayStation 3.

A system, a method, and a portable game device for playing a video game is provided. The system includes a first computing device for executing a video game. The execution of the video game is designed to produce processed interactive program instructions. A second computing device that is portable is provided. A wireless communication link capable of being established between the first computing device and the second computing device is included, wherein portions of the processed interactive program instructions are communicated to the second computing device to interactively play the video game at the second computing device location.

Alors on peu penser plusieurs chose de ce brevet, manette sans fils via la PSP ?
Ou encore jouer comme le fait déjà la GBA et la GameCube..
