I agree... you can't really leverage the 7.1 unless you have a pretty large/long room... the 2 sides will be so close together, I would argue it may detract from the "imaging". And of all the movies I have, I only have 1 that's "6.1" with Lord of the Rings... none of the HD or Blue Ray stuff I got has it...
I think the whole 5.1, 6.1 and 7.1 was "marketing" drive to differentiate with "more"... not even sure if it'll take off...
