The very big disappointment comes from that they promised (kind of) that they would get Fiber Scanning Displays working. What I gather is they had a sort of, more or less working, giant machinery prototype (The Beast) that was very impressive for the few who got to try it. But they never actually managed to make the tech viable in a headset form factor. Also unclear if they had more than one color... Still very curious about what they managed to accomplish on that front but I now doubt we will ever know.
