Part of me wonders if that power up for Sasuke is the Juubi itself. I mean let's face it, unless Madara put's Obito in a trance and forces him to revive him he isn't come back in human form. I'm thinking they are going to lose control of Juubi and Sasuke will sweep in and become it's host by using the scroll. Then, he'll finish off Madara for what he did to his clan. Then the true naruto vs sasuke fight will begin.
