If I remember the original email correctly it has all the codecs for 7.2.4 atmos and now all the HDCP stuff for 4K and HDR plus a tuner and connections for 6 HDMI with two outputs including ARC. The email did not mention room correction or balanced outputs and I would anticipate a slim design similar to the 975. I would expect it to compete directly with the Emotiva XMC with a similar feature set but no graphic equalizer or Dirac RC. This is from memory as I didn't keep the email and the announcements forum is lacking that announcement.
