Manga is still going so they will probably just continue that in another season later. Good quality animation is not cheap and they cant get too close to current manga chapter if they want to avoid fillers.
Probably. Maybe anime would end in different way than manga, that happens sometimes. Right now it will be probably just break before making another season. Story in manga is pretty intense. I think it would be hard to include some fillers and it would just water down anime like most of them.That's the reasoning behind it ending? Well I also heard that animes now will only be limited to 12-25 episodes. Same goes for OVAs, 2 or so. I just want to confirm it. I don't want to go ahead telling people in advance without confirmation.
