Perhaps it will be the case within the span of the coming decade or two that multi viewer screening room experiences will consist of each viewer wearing some type of headset, in the process not requiring this additional solution and also freeing up theater design to go in entirely new directions that don't revolve around dozens or hundreds of seats facing a single large screen.

You’re right that they are somewhat different, but presumptuous as I am talking about both. I am aware of work being done today that will have affects viewing 3D movies in theaters. The article here also didn’t distinguish between headsets and theaters, it incorrectly declared all 3D dead.
