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.

It's not 4K, it's Ultra HD

As the link in the article points out, it is Ultra HD. 4K is a different format used by cinemas with a different aspect ratio and more resolution than Ultra HD.
Ultra HD is more than enough, but it is not the same as 4K.

Wrong. 4K is a resolution, UltraHD is a format. UltraHD, among other things like colour spaces and framerates, specifies allowable resolution, specifically 4K and 8K. These are typically referred to as 4K UHD and 8K UHD.
Both 3840x2160 and 4096x2160 are considered to be 4K resolutions, as are a variety of other resolutions that are roughly 4K pixels wide.
