Before the XONE was even announced, we got a leak of a ton of internal slide about the console (still called 720). These slides where later on removed by Microsoft, showing that they where real.
The interesting thing is that they show how the "Every screen is an Xbox" thing was always the plan, and is not due to the decline of console sales, considering that at the time they where in an incredible position.
Making the hardware optional was the plan all along, Xbox wants people to access their content on every possible screen using the Cloud. Isemore convenient to them since they get 100% of the revenue without having to sell you a console at a loss. Is just talking (way) longer than expected.
With that being said, the Cloud is growing 50% every year, and im sure they are going to expand it to even more devices.
