I still don't understand this obsession/delusion with Sasuke winning. We already know what is going to happen. It's been obvious from the very beginning. I think everyone should just accept the fact that Sasuke has no counter for TnJ and PnJ.
These techniques cannot be burned or blocked. They cannot be absorbed or copied. They do not require hand signs (or any chakra for that matter). Even if Sasuke uses Izanagi to counter one, Naruto can reuse TnJ or PnJ indefinitely. The mightiest of characters in the series have all fallen to these techniques, and Sasuke will be no different.
Naruto is going to convince Sasuke that, after all of these years, he is wrong. Sasuke is going to run off again and rebuild his clan. At some point, though, his clan will betray him, and Sasuke will change his mind again. He will spend the rest of his life laying the foundation for the next Great Ninja War.
Generations after everybody is dead, Sasuke is going to be brought back to life by a weak, little boy. And the cycle will continue forever.
