I thought that with the current software the reason that height and width are not options together is because they share too much of the same information, so it would be a waste going to the extra expense with extra speakers and amplification. Don't they both mostly take ambient non-directional information and just reroute it to those height or width channels? I assume the width channels will do less of the ambient information and help more with filling in the gaps in panning, but height channels focus more on ambient stuff.
