You know, I've been thinking alot lately about the time jump theory.
You see, Chouji is out of action or dead, Rock Lee is out of action, and I think Neji is going to be out of action soon too. The village is in a moment of reconstruction, and Sasuke is about to become one with the dark side.
What I think will happen is that Sasuke will make it to Sound Nin village....Naruto and the others will have to fall back and recover from heavy battle wounds. Then a time jump will happen.
That's what I think will happen, because it is going to take so much time for the others to recover...
