Thanks to a report that was delivered by Kotaku yesterday, new information regarding the controller design for the PS4 has been revealed. In a previous article, we noted that Sony was apparently completely redesigning the traditional DualShock controller for the upcoming release of the PS4, but according to this new information, this may not be the case.
It has been revealed that the developers who are working on the PS4 are currently using Sixaxis and DualShock 3 controllers with the system. With this being said, it can only be concluded that the controller for the PS4 will have the majority of the basic functions that has been delivered with the PS3's DualShock 3 and SixAxis controllers.
In addition to this information, it has also been stated that there will indeed be a new controller developed for the PS4. This controller will apparently keep many of the features that are seen in the current controller, except for one addition. It appears that the controller for the PS4 may feature a touch-pad similar to the one that is found on the back of the PS Vita. It has also been stated that this controller will retain the capability of motion sensing, which is available through current PS3 controllers.
