Two videos of the preview of Windows 9 give hope to Microsoft and the Windows Desktop.
They have finally integrated some long wanted features into the desktop. For example, a standardized Notification Center, multiple desktops (behavior similar to Mac OSX), and downscale of the Metro interface.

Along with those; the rumored integration of Cortana will make it a completely competitive desktop to Mac, Linux, and ChromeOS.

With the addition of Microsoft’s relationship with Osterhout Design Group. ODG has some amazing tech including Augmented Reality glasses (http://www.osterhoutgroup.com/)
Which will hands down beat Google Glass and Oculus Rift as the interface of choice.
