I can think of one immediate good thing to come from HDMI 2.1. The cables that are guaranteed for 48GB/S will be perfect for HDMI2.0a systems to resolve any doubts about wether the cables can do 18GB/S or not. As for 8K. It's a laugh. I don't hear anyone complaining about lack of resolution from 4K at the cinema so why the hell do we need 8K for a domestic solution?! They're having a laugh I teel ya. I can understand the upping of the bandwidth for things like VR and frame on demand update feature is great for game latency. 48GB/S would allow some serious VR resolutions and frame rates to be supported but from what I can see today there is no practical reason for waiting for 2.1 if your target system feature set is 4K and all the features of UHD disc.
