If the 3D glasses weren't so expensive to make, I'm sure Universal would be all over it.Hopefully by 3d he means "so realistic that if feels 3d". I think by now Universal could sell unique designed 3d glasses that can work for each ride and all you have to do is walk a few feet from each other.
When I worked attractions there, we were (and they still are) under a lot of pressure by management not to let a single pair of glasses escape the building. The reason why? They cost $12 to make PER PAIR (at least at the time).
