I really do not know. But what I can say for sure is that during the installation of Debian, it allows you to choose the desktop environment at installation time, so you can have your Debian with KDE at minute 0 after installing it.
On the other hand, remember that Kubuntu is derived from Ubuntu. I don’t see Ubuntu fans very enthusiastic about creating another Debian-based distro with KDE preinstalled when they even offer it (live images) to you here.
