You might be right about Gnome but you're wrong regarding Wayland. All distros are moving towards Wayland, especially since Cononical abandoned MIR. They decided in the last minute to not default to Wayland for 18.04, instead staying with X. However it will probably be the default for 19.04. There simply is no future for X, it will slowly be phased out. Now even KDE Plasma is working quite well on Wayland from what I've heard.
