I believe this chapter should have been called: If these guys can do all this, why didn't they use these earlier?!
So most are showboating, while others are more humbly using deadly Jutsu. I get the feeling Sakura might have unintentionally either caused the death of Tsunade by nicking Katsuyu, or saved her, because the slug will let Sakura know of her predicament. We will have to wait and see on that front.
So the flashback panels of Naruto and Hinata... it's like cmon, surely this confirms Naruhina, unless one or both get horribly murdered in the next few chapters?!
Team Guy seem to be taking five here, probably feeling like they need to formulate a new strategy now they're a man down.
As for Madara, he's most likely just watching to see how this will play out, and waiting for a very intense battle with Hashirama, in which neither of them will actually die because they're both undead. Obito and Kakashi are clearly reminiscing about the old times right about now. That's gonna be another hundred chapters at least.
Well, Sai's performance in this chapter did leave a lot to be desired. Naruto should have said to him:
"Sai... I thought you read the memo... It basically says that... when we get Sasuke back into Team 7, we, um... You're out, Sai. I'm sorry, it's just we have our main guy back, and the deal was you were his substitute."
