Rumour has it that Google wants to ditch X. If that is the case, no other GUIed nix software will run without a rewrite.*
Not exactly: few modern GUI applications are written to use Xlib directly. If Google ditched X for a new window system and then ported GTK+, Qt, and a few other widget toolkits to their window system, a lot of software would run with relatively few changes.
