2018 has even more hype potential then this fall season with all the mainstream titles running anime, Jump and Shueisha are gonna have major competition. MHA will be back along with this Soul Hunter remake, BC and Food Wars will still be running for a good amount into the new year and TG is coming too. Obviously, you have your OP/Boruto/DBS long runners. But WSM and Kodansha have their top 3 sellers from the first half of 2017 running animes next year so to think this fall season have 3 popular titles (BC, Gintama, Food Wars) next year it's gonna be even crazier. By then the viewers should have a grip on BC as well as its ratings, if they extend it past 51 it could be ongoing when MHA runs which is better business for them.
