Nice MacDiddy, that's helpful.
I'm not sure I'm sold on a different speaker configuration to Atmos, because we'd either have to move our speakers when we select a different sound format, choose a compromised position or most likely choose one and stuff the other.
Hopefully they'll have a re-think, but I think in the mean time i'll wait for the DTS receivers...I'm guessing 2015, maybe 2016 unless some really good material comes out for Atmos *dance4*
