I could've sworn that this was already mentioned in this forum, so I went to look for the discussion of it and noticed that there's been no mention on it.

Well, season 2 of this series is coming out in Spring 2017:

The staff of the Attack on Titan franchise revealed at the "Shingeki Matsuri" event on Sunday that the anime's second season will premiere in spring 2017. The announcement also reveals a new visual (below) and the second season's staff and cast.

Can't wait.
