Yes. But it does not mean much. Kubuntu is basically just KDE with Kubuntu
branding. The team is comprised mostly of KDE developers and Canonical has
only minor representation. It has always been that way. What this means is
that Canonical is re-assigning developers and has been devoting its energy
to Unity. They have never wanted Kubuntu to succeed, so it is no surprise
that it has not lived up to their expectations. Kubuntu has always been the
unloved child.

I would not be surprised to see at some point down the road further
distancing of the other *buntus as Ubuntu wants to establish itself as a
brand and not just one in a crowd. I think that Canonical's vision is to
make Unity like Android. It is Linux underneath, but they do not want
anybody to know. This is just personal opinion.
