One piece, Boruto, and Dragon Ball Super were some of the last manga based anime to air year round. Shueisha pretty much went full seasonal for all the new manga works due to demands of not only fans but the overwhelming demand for "quality" animation. The model for anime original advertising however is still all over the place. there's still quite a few year round and half year shows instead of 12 episodes for quite a few toys and videogames.
