Lol that's possibly the stupidest thing I've ever heard first your saying Sasuke>Naruto then saying Sasuke will beat Madara and Obito become the Juubi host and then go on to become Hokage after Naruto's death...Kurama < Juubi genjutsu and he's out of chakra. That's irrelevant. Naruto's toast without someone stronger like Itachi or Sasuke coming around. Alliance just got owned by Madara as well. Plut jutsu is needed to end Madara or Juubi. Perhaps Sasuke will become the host as Obito implied earlier or after Naruto's death he will become Hokage? Beats me.
Here's what's more likely to happen Naruto and the alliance army beat Obito and Madara then Sasuke dies and Naruto becomes Hokage,
Naruto=main character the series is called Naruto not Sasuke.
