Depending on which analysts you choose to believe, Windows Mixed Reality headsets will either sell strongly, outselling the Oculus Rift by two-to-one and the HTC Vive by ten-to-fifteen percent in the fourth quarter... or get off to a slow start, with VR remaining niche.

On the more upbeat side is market research firm SuperData. SuperData points to the advantages of Microsoft's platform: low-price headsets (ranging from $299 to $499) and lower hardware specs (a basic experience will work on machines with Skylake-integrated graphics, though more advanced titles will require discrete GPUs). The inside-out tracking of the Windows headsets also makes for easier installation: no need to mount base stations on the walls or anything like that; just plug the headset in and go.
