Is South Park finishing?

I've just watched the newest episode of South Park (You're Getting
Old) and thought it had a lot of signs signalling that South Park was
ending.

Stan leaving the group, his parents divorcing, them moving house,
Cartman and Kyle becoming friends (!?) all seem to be sure signs that
there won't be a whole load of episodes left.

Even the episode name might be a hint. You're getting old. As in, the
show is getting old? Maybe?
