The Kinect ride started back in 2009 and lasted 5 years, forced all the way up to the next generation of consoles. A major reorganization of the Xbox team happened after the departure of Don Mattrick in 2013. Kinect is no longer advertised or bundled with the console. Today in 2016, Phil Spencer is still trying to recover the Xbox brand's image.
