I don't know who this guy works for, but employees for a semiconductor component supplier won't know anything about Microsoft's plan for Kinect.Don' think that will effect the Durango hardware,and #2 AMD guy said Kinect 2/V2/2.0/whatever will have standalone version,that means it will not be required for Durango(if what he said is true).
Plus has any hardcore(from internet) ever pleased Microsoft hardware?
Anyway i bet the Durango OS will use less power than PS4 OS
