These last chapters have felt, how to say it, somewhat rushed to me. Not that the pacing is too fast or thatthe story is losing quality, but that Kishimoto is (maybe) eager to finish the manga, so he's killing Akatsuki members quickly and making it clear that Naruto is somehow connected to the Fourth...

Think about it. Last two chapters not only killed Hidan, but also had Naruto silluetto-ed by the Fourth and that. Developments that would have usually taken weeks and weeks and weeks now are taking place over two or three chapters.

On the other hand, all I said has been said before, too. Back when Sasori was killed, for instance. And lo! In comes Sai and a whole new arc and the manga keeps on going. So who knows, maybe the Akatsuki will get even more reinforcements (gee, what an amazing number of evil, powerful ninjas!) or maybe they'll even rescue Hidan.... I mean, he's just buried in the ground, bored, so why not?
