Microsoft is planning to hold a special Windows Mixed Reality event next month. The software giant has started inviting members of the press to an event on October 3rd in San Francisco, and the invite teases an “opportunity to hear where Microsoft is headed next.” Microsoft’s Kinect and HoloLens inventor, Alex Kipman, will be speaking at the event.

Microsoft is likely to focus on its range of Windows Mixed Reality headsets, ahead of their availability on October 17th. Mixed Reality headsets will start launching next month alongside Microsoft’s Windows 10 Fall Creators Update. The first headsets include pricing at $299 from Acer, HP pricing its own at $450 (with motion controllers) and Dell / Lenovo pricing theirs at $349. Asus won’t be releasing its Windows Mixed Reality headset until Spring 2018, despite showing off its unique polygon design at IFA earlier this month.

The Verge understands Microsoft won’t be showing off a new version of its own HoloLens headset. While Microsoft is currently developing a second HoloLens with a dedicated AI chip, the successor to the original HoloLens might not arrive until as late as 2019. Microsoft has reportedly shifted its launch schedule due to a lack of industry competition.
