I'm curious about some of the developments with home theater receivers offering up to 13.2 channels:
9.1 = 7.1 + front-height
11.1 = 9.1 + front-width
13.1 = 11.1 + rear-height
I haven't seen anything about updates to Blu-ray to produce a discrete signal above 7.1. So "height" and "width" has to be derived through a matrix decoder approach. Much has been written about out-of-phase information in stereo recordings being recovered into surround channels, but how do you get "height" or "width" out of 7.1 to derive between 9-13 channels?
It also seems that only mini-monitor type speakers would be practical if you need to fit 13.2 channels into a listening room! Planar fans like myself may never get beyond 7.1 due to the space and amplifier power those things take.
