The landscape is extremely fragmented and everybody who is not on the Gnome garden will suffer a lot. Red Hat is one of the main contributors, and they only seem to care about Gnome working on Wayland (as much as I don't like their direction, I can't really blame them for following it, it just sucks that I don't like the product they're developing).
I really want to see Wayland move forward and succeed, but there are so few companies injecting money on it, they get to dictate how things move. And, as much as I hate to say it, I believe it will still not be omnipresent in the Linux desktop.
By the time GTK5 arrives Wayland will probably be old enough to drive or maybe even drink in the US.
