I wonder if they'll be including HDMI 2.1 now. I imagine that'll definitely be in the flagship model (next year?) but could it be a little something extra added to the 976, too? The initial release cited HDMI 2.0a and a followup later on updated it to HDMI 2.0b, HDCP 2.2. With the final 2.1 spec locked in earlier this year, maybe they took advantage of the delay and will be incorporating it. That'd be a nice bit of future proofing and a definite selling point for their new processor.
