Are you saying PS4's additional graphics hardware gives it no advantage over Xbox One? Kinect2 has significant hardware advantage over PS4eye and because of it, Kinect will be unmatched in almost all features (automatic & hands free login, gesture recognition, heart rate monitoring, overall accuracy due to higher resolution (1080p vs 720p), sound source detection, etc.). Sony can't match this unless they release a revised version.
As for the "simple voice recognition", Sony will need to either build a service from scratch (think bing/tellme, Siri, Google Now) or buy/license something (Dragon, Wolfarm Alfa).
And even when they do it, they will need to dedicate hardware resources for processing which Kinect2 includes and PS4 eye does not. That will quickly erase their current GPU advantage.
This is simple truth similar to 18CU vs 12CUs when it comes to their respective GPUs.
I have possibly corrected you at every single instance of you equating Kinect and PS4 Eye yet you keep on posting the same thing again and again for inexplicable reasons.
Not sure what you are trying to argue here, I didn't mention the PS4's graphics advantage and it has nothing to do with the camera peripheral.
The PS4 actually does the 'automatic & hands free login' or face login as its commonly known as instantly and seamlessly, I don't see any advantage the kinect has in this regard.
Gesture recognition (PS4 doesn't do these at the time of this post so can't make any direct comparison -referring to OS UI/menu gesture controls)
Heart Rate monitoring, I use this as an example of Kinect 2.0's advantage over the PS4 Eye myself, glad you picked that up.
Yes, higher resolution.. I posted that just above also.
Sound Source detection - software side both have same 4 channel mic array.
Sony has the option of releasing a revised PS4 camera, yes that is true.
I don't see why a GPU would be doing PS4 camera calculations, or why the PS4 would need more hardware to do something it already does with the current camera.. But who knows maybe this revised PS4 camera you speak of might be bigger and chunkier and include the additional hardware you believe it requires for calculations?
What have you corrected? You literally copied my points as to what the Kinect 2.0 advantages are and then added your own which aren't backed up by any sources.
