Microsoft's strategy is to make Windows the center of gaming and entertainment in all rooms of your home - including the office and your living room.
To that end, they are attempting to make the Xbox simply the vessel by which you use Windows 10 in your entertainment space.
If they are successful, they will continue to offer an Xbox-style machine for many years to come, or license others to offer similar machines based on Windows 10. If they are successful, it will be Sony that stops offering Playstation devices, or offers Playstation devices running Windows 10.
If they are not successful, I expect them to conduct a slow withdrawal from the games space, perhaps simply leaving the Xbox software platform as a part of Windows 10 for those developers that want alternatives to Steam and EA Origin.
