It's interesting reading startup literature regarding MVPs and iterating quickly and notice that almost none of it applies to the AR/VR space. Between Magic Leap and Ubiquty6 it seems like the most interesting players in AR are more notable for their funding rounds than for anything else. Magic Leap is rolling out their own hardware so it's more understandable but its really hard to justify spending $2K on a first generation AR device.
If I had to put money on it I think Magic Leap will go the way of General Magic, lots of cool tech and ideas in a product that was ultimately too expensive and too late to drive the company forward but will be looked upon as a great innovator once another company uses their inventions and packages it in a low cost, user friendly interface.
