I believe the controller and ps4 talk/poll eachother 10x-100x faster to reduce latency for 1st person shooter crowd.and overall responsiveness.(the controller is also passing stereo audio in both directions so yes, its the highway that uses lots of juice.)
February and supply is still short. It's not like we didn't call it.Kinda disappointed nothing really happened between November and today. Not a lot of cool games or things for the camera, or system updates.
