I doubt they will need 40 chapters to make a third season. By the end of season 2 there were approximately 40-ish or so chapters, but they may only need 20 or so. At the beginning of the anime, they did roughly one episode per chapter (so for 12 episodes 12 chapters). Later on, they started to do a chapter-and-a-half to two chapters per episode because season 2 was wrapping up.
