Obviously the marketing of 5.1 is simply that more is better.
If it were done in relation to what could give you truly
continuous and lifelike surround sound, then they would be
pushing 7 or 8 channels.

6.1 and 7.1 are indeed becoming increasingly available on A/C
receivers.

Which they of course will once
5 is firmly established. Anybody think 16 might be better
still?

I believe 10 (or 12?) channel setups to have their advocates.

The Wavefield Synthesis system demonstrated at the June AES Conference in Banff
used 88-channels to great advantage. This allowed a pretty realistic experience
while walking aroundin a small demonstration room about the size of a typical
shoebox listening room.
