I love the whole Obito being Tobi thing. If the utterly lame theory of someone controlling Obito's body is true, I'll get upset. Especially if it's someone that has basically only been mentioned once, like Izuna or Kagami.
Of course I don't think this is the case, because of the Obito flashback we had last chapter, but still, the fact that some people prefer that theory over Obito being Tobi is beyond me.
Still, the Chunin Exams was the best arc if you ask me, and there are many things that bother me about the Naruto manga that is not related to either Tobi or the current arc.
