There are definitely anticipated, new manga adaptations next season (March Comes in Like a Lion, Drifters), and definitely original coming (Izetta, ClassicaLoid).
That said, with more Iron-Blooded Orphans, more Haikyuu!!, more Strike Witches, Mysterious Joker 4, Natsume’s Book of Friends 5, Teekyuu 8, it’s definitely a season of sequels and follow-ups.
