Although Xbox One can not be found at Microsoft online stores in the US, online stores in the UK say that the console is already sold out. Xbox One was first launched nearly 4 years ago at a price of US $ 100 more than the Sony PlayStation 4.
This price difference is one cause Sony can lead in the console market with its PlayStation 4. Microsoft lowered the price of Xbox One by not packing the Kinect sensor. This they did 6 months after the launch of the console.
Although sales of Xbox One can not match the sales of PS4, Microsoft has re-focused its attention to providing better games and consoles.
