Not necessarily...wayland is for real and it may well just become a lightweight alternative to traditional X and not replace it.
It may become in the future but right now there is not even a single somewhat mainstream distribution that even ships Wayland. First Wayland 1.0 with a stable API has to ship, then toolkits using that API have to ship, then distributions have to ship it along with Wayland-compatible SDK files, and only then can applications adapt to it.
Phoronix reports thoroughly on Wayland. It should be clear that distributions will start to pick up Wayland in the coming autumn cycle and ship compatible toolkits in the spring cycle. Not a single Phoronix reader can seriously ask before mid-2013 if anything ships with Wayland support.
