all right, there something i just noticed, in shippuden naruto hasn't gotten a 1vs1 against anyone. its either he's fighting with back up from the get go or people will interfere...ususally main character get 1 on 1 to show their stuff, but that's not the case with naruto, and at this point i think there is no one left before sasuke, so we can just conclude that naruto 1vs1 will be against sasuke
