Audioholics has a first look on the 975 by the same reviewer that did the Emotiva UMC-200 preview. I don't believe either unit has shipped yet. The UMC-200 has auto-eq and multi zone which were already pointed out. It also has USB that accepts the Emotive dongle only. On the downside it only has HDMI input and output, and my cable box doesn't output HDMI. There are component to HDMI converters available, but they add to the cost and the complexity of the system. I'm looking forward to reviews of both.
