I don't know Jim. 3D has been around since the 50's and while it seems to have caught on recently, do you think most films need 3D? I understand why blockbuster films like the Hobbit, Avengers, or even Prometheus need to be shown in 3D, as they excite audiences with incredible images and 3D does offer that experience.
But what about films like Beginners, Social Network, or Girl with the Dragon Tattoo where action is not the primary concern but rather story, dialogue, and themes? Would they need 3D to convey their story better? I don't think so. To see in color is a huge change just as hearing audio in films for the first time is extraordinary too. But to have 3D, become the new standard for film..... just isn't sinking in to me.
