User blog comment:Manuel de la Fuente/Attack on Titan Season 2: release date, facts, rumors, and everything we know so far/@comment-28004226-20160418185136

Whoa hold on a minute since  Season 2 will cover the events of the  Clash of the Titans  and  Uprising  arcs. How do we know that? Just do a simple math: the first season of 25 episodes adapted the first 34 chapters of the manga, so assuming that the second season would be of the same length, it will cover the next 34-35 chapters, until around chapter 70. That's the whole Clash of the Titans and Uprising arcs. In chapter 71 begins the current  Return to Shiganshina arc  which is still in progress and obviously cannot be adapted yet.

Just why won't they release season 2 already, i mean the manga will be ahead of the anime already by then!!!!!
