I can't add much of value to this, but just wanted to say thanks for the posts on the beta units and the pictures - great to see it is out into people's hands.
Summary of what I read, same specs thus likely same speed / performance. Likely improved from 5 tuners to 7 tuners (based on the writing on back of box).
No extra storage, and access card moved to the side (likely just for consistency with other next-gen receivers (H44 / client boxes).
External appears to be much the same except the removed access door with the access card / reset button moved to the side.
