“Can I use the PS3 3 controller on the PS4? I own like 4 of these controllers and they weren’t cheap. Will the PS4 support the DualShock 3?”
Unfortunately you will not be able to use the DualShock 3 controllers on the new PS4. The PS4 will support the new DualShock 4 controller. The new controller comes with several new features – clickable touchpad, motion detection support, Share button, and a light bar that can display a variety of different colors.
