After six months of trailing behind the cheaper PS4 in worldwide sales, Microsoft announces a new lower-priced Xbox One bundle with no Kinect sensor in the box. With PS4 price-parity, Xbox One sales significantly improve.
Prior to and after the mandate, all Xbox One consoles initially shipped with the Kinect sensor included. On June 9, 2014, cheaper Xbox One bundles were introduced, which did not include the Kinect sensor. Microsoft stated the decision to offer Xbox One bundles without Kinect was to "[offer] a choice to people that would allow people to buy an Xbox One and then ramp up to Kinect when they can afford to", while also allowing games to use processing power that was previously reserved for Kinect. An updated Xbox Development Kit issued in June 2014 allows developers to explicitly disable motion tracking functionality in games, allowing access to additional system resources that represent about 10% of the GPU processing power. These resources were previously reserved for Kinect skeletal tracking, regardless of whether the Kinect sensor was attached or in use.
