From an extensive review
"The Microsoft HoloLens 2 is available for preorder today for $3,500, and it’s expected to ship later this year. However, Microsoft has decided that it is only going to sell to enterprise customers who want to deploy the headset to their workers. As of right now, Microsoft isn’t even announcing a developer kit version of the HoloLens 2.Microsoft’s HoloLens 2: a $3500 mixed reality headset for the factory, not the living room | The Verge
Compared to the HoloLens we first saw demonstrated four years ago, the second version is better in nearly every important way. It’s more comfortable, it has a much larger field of view, and it’s better able to detect real physical objects in the room. It features new components like the Azure Kinect sensor, an ARM processor, eye-tracking sensors, and an entirely different display system."
