They might wait!
"And you can bet on even bigger numbers to come, as first generation flatscreen adopters prepare to re-enter the market, as part of the traditional (replacement) cycle of life."
They might wait! The *early* early adopters bought panels that supported composite, VGA, and DVI, then got the royal screw job when "they" decided for rights restriction purposes that most HD devices would only actually output HD via HDMI. They then had to buy quite expensive adapters to use the panel properly. I've heard of plenty of these people deciding "Hell no I'm not buying a 4K panel just to be screwed again", they plan to wait quite a while to make sure HDMI 2.2 is REALLY all they need, that they won't just decide in 6 months "Well, actually you need HDMI 3" or something.
