The manga isn't over yet. They can still tie in the other clans of the narutoverse into what has become the main storyline now. Especially with this Yin-Yang stuff. As far as we know the Hyuuga's techniques are somewhat based around Yin-Yang and so are the Nara's and Akimichi's, right?

It is lame that Naruto pt.1 basically ceased to exist though. If it wasn't for pt.1, pt.2 would be alright, but still pale in comparison to how much better paced pt.1 was (I don't really think it was that much better). Oh well.
