Microsoft’s PC partners have been gradually unveiling their Windows Mixed Reality headsets at IFA this week, all promising vague fall or October release dates. Microsoft is now officially revealing that the first headsets will be available on October 17th for consumers, alongside the Windows 10 Fall Creators Update.

Mixed Reality headsets will start at $299 from Acer, with HP pricing its own at $329, 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 this week. It’s the most expensive headset in the range at approximately $535, and it’s not clear why the company is releasing it months after competitors.
