HDMI specifications are overseen by the HDMI Forum, a non-profit industry consortium. They announced version 2.0 which includes a number of changes. The most recent version is 1.4 and likely that is what most of your equipment is including your cables. They say that 2.0 will not require new cables. However chances are your equipment may not be upgradable. Some vendors such as Sony are indicating that firmware updates will be possible with their equipment. The new specification will bring the bandwidth up to 18 GigaBits per Second! This is enough to pipe through a 4K video up to 60 frames per second (assuming you have a compatible TV) – enough for 4K 3D. Another neat possibility is that HDMI 2.0 can support dual HD video streams at the current lower-resolution. And your current 1.4 devices should work with 2.0 no problem, it is supposed to be backwards compatible. We should begin seeing HDMI 2.0 products in 2014.
