The Model 978 will have Audyssey of some form, not Trinnov. In both cases, though, the bigger question will be how many channels of D/A conversion will be supported. The AV7005, for example, has pre-outs for 11 channels (including height channels and "wide" channels), but only eight channels of DAC's. As a result, the room correction only has to operate with seven speakers and a sub at any given time.
