I think he's reviving nine and a half tails. But he likes to round up.
Anyway, say what you want, but I'm starting to like Sasuke a bit more. He says he's still seeking the single-minded revenge, but he feels a bit less emo and he wants to learn of things bigger than those he sees right in front of him. Naruto dreams of things bigger than he sees, so I guess they are kind of more equal, even if in different ways (knowledge, ideology). I also like the fact he doesn't bother to listen to aimless prattle and just does what he wants to do. Though it's too early to say such things about Sasuke, but those are signs of bigger men. I find it pleasant I don't feel like I need to keep hoping Sasuke gets no scenes.
