First off in my opinion the plot was diminished a little because of Tobi being Obito which I still have reserves that Obito was the Tobi that fought Minato.

If Everyone was paying attention to the whole story Madara died after the final battle and not during the fight between him and the first. The story even stated that Madara may have planned that battle and knew that he couldn't win so he was only to acquire the 1st Hokage's DNA. From then on the story is pretty shady Madara may have lived through the 3rd great War according to the last Manga because he know of Nagato as well. It seems Obito is Madara's subordinate because of his reaction when Madara arrived and not even Naruto sensed him coming. This is definitely not the climax of the series especially because Madara stated that Obito was a clone and that he was a clone too. Please tell me what what you think about the new storyline the plot will get instructing because of Sausake's story as well. Everyone is getting used like a tool or should I say like a Ninja....GO...IKU
