When I think about it the idea that a Naruto vs. Sasuke battle will be the conclusion just seems like such a letdown from the present battle. Sasuke is no match for Obito, half as much as for Edo Madara, either battle he would lose badly. Presently Naruto is much stronger than Sasuke and that amount of power is still not enough to beat Obito, Edo Madara and the Juubi. So to have a final battle with Sasuke seems to anti-climatic for me, your guy's thoughts?
