Earlier this week, KDE developer David Edmundson described in his blog how KDE would be tied to logind and timedated but not systemd itself, at least according to his claim that "The init system is one part of systemd that doesn't affect us at all, and any other could be used.".
Later, in the blog comments, he clarifies that starting with plasma 5.5, in 6 months, they'll drop "legacy" support, according to a decision taken in the plasma sprint.
Even if one can only guess why there is no formal announcement, it seems clear - unless somehow there is a shim or emulator, not only for logind but also for timedated, in 6 months KDE will be unusable unless you are running systemd. And the blog entry makes it clear that the plan is to remove more and more functionality from KDE and use systemd instead.

They will just use XFCE by default. I think you can select it at install time anyway.
I actually prefer it to KDE.

Doubtful. They are building their own desktop called Lumina, based on QT and Fluxbox. I'm pretty sure it's going to be the default if KDE gets dropped.

Correct; and Lumina looks more important as Razor-Qt and LXQt have slowly soured on the vine.
