A few days ago it was announced that Shinkalion will end in due course. It will likely end in June, obviously coinciding with the end of Zoids Wild, another anime by Takara Tomy and TBS. It is currently not known what will happen to the timeslots of both series, however given the prospect of two anime ending at the same time and no succeeding anime announced to fill the gap at that time, it might happen that TBS' anime block gets dissolved for now.
