That's a fair point. I admit I was judging by the availability on the PC side (I don't follow the console market).
Although, if I'm not mistaken, my particular PC monitor initially didn't support HDMI 2.0, even though it's a 4k panel. There was a further revision which included it. I have that revision, but support is still somewhat wonky, in that it can't seem to switch on its own from 2.0 to 1.4b.
Display support is always last in this chicken-and-egg problem. As far as I know, there's still no DisplayPort 2.0 supporting displays, so any of the higher end monitors require display stream compression. I can't even get a DisplayPort 2.0 MST hub so I can chain multiple 1440p@144 monitors. Which is definitely something that HDMI can't do.
