The reason you will switch is that plain X11 goes unsupported and will not work on modern systems.
The initial thing you will switch is not Wayland proper, it's just X11 sitting on top of Wayland. Thinking of Wayland as a competing display server is as of now not really realistic -- it's much better to think it as a refactoring of the internals of the system that uses X and compositors, taking the parts of both that need privileges on the system and really fast communication and merging them together in Wayland, leaving the rest of the parts into X.
Which X11 features are still missing? Does Wayland support X11's seemless remote multiuser sessions already?
I've googled around and found this fresh message from April 2012:

"... X11 support on Wayland. It's basically ready to go, but window management is implemented only as a hack right now."
That doesn't sound good. It seems that Wayland will have a hard time to replace X11 in the next decade. Currently I see no reason why I should switch.
