I have the ultimate setup for the Hobbit. On one side of the hall, I have one of the biggest IMAX Digitals; the image won't be superclear but it'll be superlarge and have amazing sound. On the other side of the hall, I have one of the 48FPS digitals in a midsize theater with good sound, that should provide the clearest picture I've ever seen in my life. I've already recommended to customers that they see the film twice, as I will.
(The only thing I don't like about the 48FPS is that it's going to be physically huge. A 2D film usually takes up between 80GB and 200GB, although longer films like "The Dark Knight Rises" pushed 400GB. This beast, being 3D and 48FPS and long, will probably take around a Terabyte... and, despite the advances in computer storage, it's going to hog up all the space in the drive for that projector.)
