Microsoft has officially started the sale of  the new visors compatible with its Windows Mixed Reality platform.
Previously announced models are now on pre-order on the official website microsoft.com or in the USA Microsoft Stores. Actual availability will be from next October 17th, with the avaialbility of the new distro Windows 10 Fall Creators Update, required for using the new Mixed Reality headsets.

UPDATE (September 22nd, 2017):
Windows Mixed Reality platform comes in two flavours; a standard edition that can work on low specification PC hardware and the Windows Mixed Reality Ultra format, which allows the same head-mounted displays (HMDs) to use more powerful PC hardware to deliver richer VR experiences. In a hands-on with the consumer edition of the Lenovo Explorer, it does appear as though Microsoft has established a welcoming multi-purpose VR platform.

Within Microsoft’s global strategy, Mixed Reality concept defines and involves devices like Hololens, from Microsoft itself, that are more properly for augmented reality. About virtual reality instead, Microsoft leverage its connections with a series of hardware producers (Lenovo, Acer, Dell, HP to begin) for new devices and visors. For the IFA 2017, Microsoft released some news from its website: https://blogs.windows.com/windowsexperience/2017/08/28/windows-mixed-reality-holiday-update/ .
Between others, maybe the most interesting news is the Steam support for all the Windows Mixed Reality devices.
