Now when a series reach around the 100th chapter become an anime, this is the same for NuraMago or KamiNomi but yeah, for Beel probably they went ahead cause when the anime start the manga will be around the 90 chapt, that's probably cause the had many things ready (like seiyuu, studio, ecc.) cause the little OAV for the Jump Festival
But well for all this series if have a fast ending (26 epi), i hope for a future season another time, probably they're tired of fillers and now choose to make more break (i wait always next Gintama season)
