Since no movies are being encoded with discrete "height" channels, as a previous Yamaha owner, this just looks like the feature of extra "presence" channels revisited and now gone more mainstream as Dolby has something else to license. Sound will be primarily extracted from the existing L/R channels and some from the center in one form or another probably altering the phase a little bit and placed in to these elevated speakers. This even reminds a little of the pre DD and DTS sound days when designated 70mm theaters use to add an extra pair of speakers in the front. Sounds like marketing to me and I am not getting too excited about it.
I am wondering how people are going to react to the idea of adding even more speakers now that they are labeling this a "9.2" set-up?
