Hmm, we didn't see the underground fortress of solitude of Danzo after the blast. I expect him to have a real bad-ass army that makes ANBU look like a bunch of genin.
Loved the last scene how Naruto entered, on top of a toad that is on top of gamabunta and the two other mega frogs besides Bunta.
In the preview for next week, it seems Naruto learned that Kakashi is dead... (DBZ reference: Gohan goes frantic when he sees that androd 's head is crushed)
And where is Sai?...
Edit:
For the fans (including me)
