Here is Walter Murch's assessment
Why 3D doesn't work and never will
From Wikipedia:
"Murch is widely acknowledged as the person who coined the term Sound Designer, and along with colleagues developed the current standard film sound format, the 5.1 channel array, helping to elevate the art and impact of film sound to a new level. "Apocalypse Now" was the first multi-channel film to be mixed using a computerized mixing board." He won two more Oscars for the editing and sound mixing of "The English Patient."
