No, actually I think Tsunade has a better chance of being left behind to be the mourning queen in her tower, at least until Naruto is mature enough to take her place. Even if he does beat Akatsuki, no one's gonna give him the Hokage spot NOW, not with the way people distrust him. XD He's too young. Gaara is his age, true, but he spent those two years with his people, gaining their trust. Also he's still and quiet, so he comes across as thoughtful and thinking deep thoughts. Naruto... not so much. XDD
