This by no means is to indicate that kubuntu is kia. It just means that it is no longer part of our day job. In fact, I personally still do the milestone testing on arm platforms (after all my other work for the day is completed mind you). And as far as LTS support goes, it will still benefit from the core updates (the same as all other community projects).
I have been a KDE user since the 2.x days. One of my many desktops that I use regularly is still kde based. My daily focus is on Ubuntu, but I still like KDE as well.
Personally, I like seeing both Unity and KDE evolution. I think they are both outstanding projects. KDE took a long time to get where it is (well polished), which shows the determination of the community behind it. Unity is getting there a bit faster, but having full time engineers helps it grow immensely.
I firmly believe that both have their place in the Ubuntu community family.
I will continue to test it in my spare time, when I can.
