It's in a paragraph about KDE Software Compilation 4.11, which has indeed been preparing for Qt 5 and Wayland by porting additional shell elements to QML and further work on X11-independence in the window manager. The Kubuntu team specifically has also been looking into packaging the stack bits that will eventually be needed; I don't know how that translates into packages in this release. Specifically in the context of a Kubuntu announcement it might be mostly there to reassure people Kubuntu isn't having a problem due to Canonical's work on Mir.
