According to a source, Sony has been trying out numerous different iterations for the controller for the next PlayStation. Some of the controllers prototypes include biometric sensors on the grips and an LCD touch screen.
Another engineer said that Sony is looking to replicate some of the features of the PS Vita for their next controller, with its touch-pad on the underside and touch-screen on the front. While the DualShock 3 will apparently not be the standard for the next PlayStation, it is likely that the controller will will be compatible with the next-gen console.
Rumors have been swirling that Sony is seeking to radically change their controllers for next PlayStation, with some rumors pointing to something that more resembles the DualShock in form factor that breaks apart to form two separate motion controllers.
