Season 2 Officially Confirmed for Spring 2017.
I take it, it will be released around April then just like the first Season was. The Manga would be around Chapter 92 by that point and it most likely be ending in early or late 2018 so Season 3 IF and this is a big IF, Season 2 ends on a cliffhanger and not have an original ending, then we can expect to see a Season 3 the next year after…surely. Right?
