A pair of pictures from dev kit for the new PlayStation have been posted online, with unnamed sources confirming their genuine nature. The biggest difference between these controllers and the DualShock 3 is a touchpad in the center.

It is also believed that there is a panel above the touch pad which lights up, giving the controller motion-sensing abilities like the Move. Other differences include an embedded speaker, a headset jack, and a contoured top for both analog sticks.
