Specification supports 4K video and 32 channel audio
The HDMI Forum is a nonprofit association that manages the HDMI specification. Today the HDMI 2.0 specification has been officially unveiled and is available for partners to download right now. HDMI 2.0 promises significantly increased bandwidth allowing new features.
HDMI 2.0 supports bandwidth of up to 18 Gbps. That gives the specification the bandwidth to
support 4K 50/60 resolution video
-- that is four times the clarity of standard 1080p/60 video. HDMI 2.0 also supports 32 audio channels along with dynamic auto lip-see and extensions to CEC.
HDMI 2.0 is backwards compatible with earlier versions of HDMI, and perhaps the best news is that HDMI 2.0 doesn't require new plugs or new cables. Existing high-speed category two cables are already capable of carrying the increased bandwidth provided by HDMI 2.0.
The HDMI 2.0 specification is available for adopters to download via the HDMI Adopter Extranet. A press conference will be held to discuss the new features of HDMI 2.0 at IFA 2013 in Berlin this Friday.

The previous version of the spec supported 8 audio channels, which current 7.1 home theatre systems max out. They wanted to bump it up to leave room for future use, what would YOU suggest that they set the limit to?
They had to pick something, so they likely picked a number of channels that they thought would be enough to last them into the distant future. The fact is that the 24 new audio channels require about 1.4% of the extra bandwidth capacity added by HDMI 2.0... not exactly causing a problem there.
"Intel is investing heavily (think gazillions of dollars and bazillions of engineering man hours) in resources to create an Intel host controllers spec in order to speed time to market of the USB 3.0 technology." -- Intel blogger Nick Knupffer
