I agree with much of what you're saying. However I'm not sure your comparison with Google Glass is fitting. The market for a functional Google Glass might also have been a lot bigger than 50 000. Not a lot of people outside the tech-environment knew a whole lot about it, and there weren't really an eco-system around it since it was never a consumer-grade product.
So I think the market is bigger than previous numbers indicate, however I'm not sure how close to perfection it would need to be to show it's true colors. Hopefully the launch of Oculus and Vive might give us an indicator this year.
(As an anecdote,) personally I would want something like this if it actually had enough content to let me reuse the product without indefinitelly replaying tech-demos. :)
