Announced on stage during the Thursday keynote at Build 2017, pre-orders are now available in the U.S. and Canada for Windows Mixed Reality developer kits from Acer and HP. Included in the developer kit is the mixed reality headset; the new motion controllers also announced today will not be included.

The price for the Acer and HP kits is set at $299 and $329 respectively. Developers can expect their kits to be shipped later this summer.

Acer Mixed Reality headset

The forthcoming motion controllers for Windows Mixed Reality will feature six degrees of freedom just like the headsets, and external sensors are not required thanks to the sensor array actually built into the front of the headset.
