I'm not sure that's true: It seems to me that mass consumer Atmos capable AVRs will most likely look much like existing 7.1|9.1|11.1 AVRs, except for the addition of on-board or external Atmos rendering technology. After all, the CEMs will initially be trying to sell their new tech to AVR owners who already have a 5.1 Standard + 2x Front Height speaker setup (or better . . . 9 or 11 on-board amps will offer the opportunity to run Atmos with additional Front Wide, Rear Surround, and|or perhaps Rear Height speaker pairs). Forcing owners of existing speaker configurations already supporting Dolby PLIIz, DTS Neo:X, Audyssey DSX, or Yamaha CinemaDSP (and perhaps also Auro3D 9.1?) to make substantive substantial|expensive speaker replacements and|or reconfigurations would likely slow acceptance of Atmos in the mass consumer marketplace...?!
So I would expect the room correction requirements to remain basically the same as they are today . . . and that we will see 'evolutionary' improvements, some of which might be suggested by Atmos issues.
