I've been waiting for basically the same thing in 3:2 or 16:10 although I'd settle for 4K, given real-world constraints. For what it's worth, that's a tremendous amount of bandwidth that even _new_ protocols such as HDMI 2.1 or DisplayPort 2.0 don't support, except DP2.0 in it's maximum bandwidth mode that hasn't been implemented anywhere as far as I know. If you take your requirements down to 4K, then both HDMI 2.1 and DisplayPort 2.0 at UHBR10 can do it.
