In my market the thing that upset me more than 48FPS being fairly widely available was the limited (once single theater!!!) availability of ATMOS -- Hobbit with its caves and rain and such is tailor made to the immersive multichannel sound of ATMOS...

It would be quite an accomplishment for someone to work out the "psycho-acostics" of using a sound bar (like the OSB-1) to recreate the spatial cues of ATMOS which has the capability to encode for 64 discrete speaker locations -- http://www.dolby.com/us/en/professional/technology/cinema/dolby-atmos-creators.html
