After reading the press release, I think the reason we're not seeing much chatter about this on the forums is who really cares?
Most of us have some sort of STB/BDP/Receiver/Speaker arrangement -- The receiver switches HDMI -- why would I need my TV to return audio signals to the receiver?
I personally don't need networking with my HDMI, I have wireless for that -- though I guess in the future consolidating the HDMI and ethernet cables I have running to my BD player and Xbox 360 might be kinda handy -- the only thing is where will the network originate? Are we going to see STB/cable modem/network switch combo's?
The hardware to make the new standard any more useful than the current HDMI standard doesn't exist, and none of us know what the new connector even looks like, much less own TV's, receivers, or source devices that are equipped with it.
Seems pretty much like a vaporware standard for vaporware devices that most people (just look at the number of people like myself who just invested mega-bucks on a 1080p TV in the past year) will not be willing or able to upgrade to for a number of years.
So what's to talk about?
