Few people seem to remember that one of the main reasons HDMI being introduced had little to do with its performance.
It had more to do with the copy protection that was bundled within the cable specification.
We the buying public were told (conned) into believing that HDMI offered perfect connectivity, flawless "digital" data transfer and that it would be the last cable we would ever have to buy.
In reality HDMI was (is) nothing more than a DVI cable with a few extra wires tacked that could be used for Audio, handshaking and HDMI copy protection verification, and more recently, audio return and LAN connections.
Being based on a video cable meant that audio was always going to be compromised. HDMI uses the video clock and audio data has to fit somewhere within this frequency and this leads to jitter (and this is the reason some companies now strip the audio data out of HDMI, re-clock it and send it down another HDMI cable).
DVI itself was never designed to run over long distances and this is a legacy passed over to HDMI.
All this being said, I believe that as long as content protection is the main reason for a connection being used, and as long as content providers believe that we are all thieves whose only goal in life is to copy every bit of media we can get our dirty little hands on, we will be stuck with HDMI or other compromised cable.
