This is probably THE most repetitive question on the site. Currently, a special episode will be airing in just a few days on New Year's Eve. The best time for an announcement.

Generally speaking, there are two more main arcs that the anime hasn't covered, plus 2 major side stories, so there is plenty of material for more episodes and the series is popular enough for a continuation, so it's likely just a matter of time till it is announced. Whether or not we want it due to the amount of story butchering is another question.
