And cable STBs are forced to fully implement HDMI 2.0 why? They could do just do HDMI 1.4 for a long time since I doubt they're really going to do 4K anytime soon. 4K roll out will likely be kinda like HD roll out. A channel or two and special STBs for the few folks willing to pay extra for the service. Even with DOCSIS 3.0 it's going to stress the plant. Even then 1.4 supports 4K at 24/30 fps. Just not at higher frame rates.
