Speaking to OPM, VP of Sony Worldwide Studios Michael Denny explained:
It's not a Move controller because the Move controller is different and will be compatible with PlayStation 4 and the new camera. The feature your talking about is the light bar and how that may interact with the camera.
Obviously the new 3D stereo camera and HD feed [will] be a lot better with AR aspects, and it can track the light source clearly in 3D so there are going to be features possible in a motion sense there. And obviously the DualShock 4 has improved SixAxis motion sensing so motion gaming is possible with the new controller.
Hooray, Sixaxis! Please excuse me while I go throw up.
