BGR picked up a rumor that the Kinect sensor of the new Xbox One console costs "almost as much" to manufacture than the rest of the Xbox One's hardware. This snippet of information was revealed in an "Ask Me Anything" session on Reddit by an anonymous Microsoft employee, who was verified to be authentic by Reddit moderators.
The employee explained that the Kinect plays a major role in the Xbox One experience, adding that Microsoft bundled the sensor with the system to ensure all developers and gamers had access to it for every game. He said that Microsoft took a gamble with the new Kinect sensor, noting that it “costs almost as much as the console to make” and “the success of the Kinect carries much more weight” for Microsoft than the Xbox One. He went on to explain that the sensor is an “integral part of the Xbox One experience.”
