Hello, long time lurker here. I understand how you feel. I felt the same way with all this talk of The Fedora Workstation with GNOME and such. I think all that is just release hype. While it is true that a lot of people believe that Fedora = GNOME, I think those people also believe that customizing GNOME = customizing your distro.
Thing is, compared to everywhere else, KDE is treated pretty well in the Fedora community. I've been using KDE on Fedora for a while and the updates are delivered in a timely fashion, the community is nice, the default "group install" gives you a very nice KDE experience and there isn't too much modification to the DE anyway. Compared to things like Kubuntu and such, where you don't get updates quickly and if you're using one DE, be it KDE or XFCE or what have you, you're pretty much stuck to it. KDE on Fedora has given me the fewest problems of any distro out there. Even on Debian Testing, KDE often crashes or becomes unresponsive at times but on Fedora KDE has been a lot more stable for me.
So while I understand how you feel, I don't think Fedora will be "ditching" KDE any time soon.
