Is it possible for the PS4 Eye to piggyback off of the X1's Kinect? I mean if most 3rd-party games rely on on the voice commands and minor camera functions, they should be able to function similarly well. Maybe that also depends on Kinect's API and some reverse development maybe?
I mean it will of course count on what the specs on the camera are, and how much system resources is dedicated to it. However having gyroscopic functionality in the DS4 should help substitute any controller/motion done on the Kinect.
Motion controls for regular games can work if it's done unison with the controller, but can be problematic if the tech there isn't utilized properly or up to the job (DualShock 3). Even though it was built in day-one, very few developers used it and very few gamers cared for it. Will that change now that the tech has improved, the PS4 is easier to program for, and with Kinect aiming for similar goals at the least?
I can see MS spending and messaging the casual Kinect gaming aspect to publishers, but how will they do with developers who implement these features in multiplatform games, and have to keep a certain amount of parity between both consoles. If that's the case, I can see developers doing the minimum with Kinect if it means giving the same opportunities to the PS4 Eye (assuming Sony does marketing for it if One/Kinect gains some serious early market traction).
