One of the reasons it gave for the drop is that Microsoft sold fewer Xbox Ones and Xbox 360s—1.6 million combined units this year, versus 2.0 million last year. Microsoft did not break out sales of its new Xbox One console versus sales of the legacy Xbox 360 console.
The other reason it gave for the revenue drop is that Xbox One had a massive price cut this year. The units Microsoft sold in the first quarter of 2014 came bundled with the Kinect camera and cost $500. Later, Microsoft unbundled the Kinect and dropped the price to $400—then dropped it again to $350 before Christmas.
