Yeah, most people saw it coming. Usually a new OP and ED would've been announced a week or two ago. Also, just like Monthly Fairy Tail Magazine, only 13 volumes of it's successor, Monthly Fairy Tail Collection were listed. So if you did the maths, the anime was clearly going to end at the end of March. To be honest, I don't think they could've avoided a hiatus anyway (even with filler), cause the Alvarez Empire arc has no end in sight, and Fairy Tail is getting into the stage where there it's very difficult to try and squeeze fillers in.
