Well it hasn't shipped for a long time, and as it stands now it's worse than its competition, not to mention they have way less resources than their competition. And probably the main reason they didn't ship until now is exactly because of all these reasons. Which means the more time they spend not shipping, the harder it will become for them to ship.

I think it's fair to speculate that they will end up as vaporware. Only alternative I can see is them pivoting to a more niche field so that they don't directly compete with hololens.

People started saying Duke Nukem Forever was a vaporware long before the parent company actually admitted it.
