I'm looking forward to object based layouts and having the ability to add at will. Hopefully there will be plenty of channels. I'd sacrifice the amp section for a dozen (more would be good) assignable outputs.
So far from what I understand <<Disclaimer
like nick said, ceiling speakers added to existing 5.1 or 7.1, max 11 channels ... 7.1.2 or 7.1.4 ,5.1.2 ,5.1.4
I hope our local store sets up a system we can hear. We have only one audio store in town. Its that or wait for Nick or BR to get it done and give us feedback.
