I think this chapter is four worthy. The art seemed better than normal, though it may just be my fascination with Obito's new form/design. It's really great.
I like that some other characters like Sakura and Hinata get some panel time, and I just love the fact that they're working together to figure out what's going on. I think the shipping wars give off this wierd idea that Sakura and Hinata hate each other and Kishi give us these panels to be like, "look, they're both bad ass and working together...please stop." I also enjoyed the fact that Sasuke had to ask Naruto what was going on, I think it's just a small thing to show how much more perceptive Naruto has gotten.
With all the Kages admitting that he is the strongest it seems to be a set up for him to be the final villian, but I don't really think so. I really think that the "Trump Card" is going to come into play with Madara. There's also that small fact that, you know, Madara has been doing this whole thing sitting down. And that it seems like he's just now starting to stand up. Scary stuff, man.
I predict that the "new kages" are going to show up to help the "old kages" because they could use all the help they could get right now.
