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 original content is most likely 24fps so 48fps for 3D would be fine with 3:2 pulldown I think its 96fps where it gets super smooth.
There are cases like Football where I would like the 120hz or better for 3D but if the source is 60hz well its just trickery anyhow.

The thing is when you get to silly high resolutions you get diminishing returns for all that effort. Other things have more impact - better colours, less blurring and higher refresh rate. 4K needs those things too or people might just prefer 1080p with everything else over a flawed 4K screen. By maxing refresh @ 60hz they have already limited what 4K screens can do.
