So this new format will add the front presence speakers to a 2.0 or 5.1 source? If this fad takes off, (Yamaha has been on board for a while now) then maybe we could get some encoding in this format. I think that it would be a more beneficial 7.1 encoding than the 7.1 encoding with rear surrounds. I bet an A/B of a 7.1 encoding with rear surrounds is hard to distinguish from that of processing 5.1 to 7.1. However, most people would have a hard time getting on board with having presence speakers since they have to be mounted up high. At least with a 5.1 setup there is no wall mounting necessary since you can get either towers and/or speakers only requiring speaker stands and be all set.
