All right here me out, I have argued against Sasuke being the center of Madara's downfall, my reason is that its the hero who defeats the final threat, but then I realized that there is one threat left after Madara, the God Tree.
My theory is that Madara will revive the God Tree this time at full power, he will somehow force Naruto and Sasuke to fight in an attempt to prove that he is right that people will never get along and the world will never change.
However after the battle Naruto and Sasuke reconcile and fight Madara together stopping him with the binding jutsu given to Sasuke by Hashirama, this teamwork represents the reconciliation of Uchiha and Senju as well as the Sons of the Sage and fulfilling the prophecy of the two powers Uchiha and Senju coming together. (This will also represent the redemption of Sasuke).
Just as it seems like its over, the God Tree will go out of control and kill Madara and attack the Alliance, then the Sage's prophecy of Naruto solving the Tailed Beast problem comes into play with him stopping the God Tree and the process deals with the Tailed Beasts once and for all. (Probably changing them so that they can never be used as weapons again).
