I am also a big fan of the entire Naruto = Yondaime's son. But that's so obvious that I'm sort of think that's he's not, just because the mangaka is a fucker like that.

I'm with you on that. Personally, I think it's something that probably will never be explained or alluded to, Naruto will just grow up and learn Shanshin no Jutsu and be Rokudaime and look a hell of a lot like Yondaime, but no one will ever say he's actually Yondaime's son. XPPP

It's like that thing about the Third Uchiha. Or Naruto's new "THAT jutsu." The manga-ka likes to play with our minds. >_O
