A new update coming to the PSP, dubbed "PSP Plus", will allow gamers to use their DualShock 3 controllers with their PSP games. Full dual-analog support will be one of the huge benefits of this setup, but rumble functionality is another benefit.
Unfortunately, only one game is announced as supporting the PSP Plus technology, and that game is Resistance Retribution. Other games may use the technology in the future, but no other details are known at present.
