Microsoft recently revealed there’s a group of virtual reality headsets that’ll be released for Windows 10. Details about the headsets weren’t abundant, but Microsoft says more information will be shared before the year is up. Microsoft’s Alex Kipman has revealed two events are being held in December between the 8th-9th and 14th-15th.

Hardware information will be shared during both events, as will details about Windows Holographic, an immersive Windows experience.

Headsets are coming from HP, Lenovo, Dell, Acer, and Asus. They’re set to roll out early next year and will begin at $299.
