Will Wayland replace X?
Wayland is a communication protocol that specifies the communication between a display server and its clients. The aim of Wayland is replacing the X Window System (Also known as X11, or Xorg) with a modern, secure, and simpler windowing system.

Wayland is enabled by default in the GNOME Desktop. You can choose to run GNOME in X11 by choosing the Gnome on xorg option in the session chooser on the login screen.
Why does Wayland need to support X11 applications?
Being able to run existing X11 applications is crucial for the adoption of Wayland, especially on desktops, as there will always be X11 applications that have not been or cannot be converted into Wayland applications, and throwing them all away would be prohibitive. Therefore a Wayland compositor often needs to support running X11 applications.
Is there a way to replace x in Wayland?
Wayland is still in development and will not replace X as the main windowing system anytime soon. the fact is that X is a mature system, it simply works and is expected to be found on Linux/unix systems, so, even when Wayland become the main windowing system for unices they should have X as legacy option.
