I feel Madara will be taken care of by Sasuke, leaving Orochimaru left to Naruto. In the end Naruto and Sasuke do whatever.
I think Guy will kill Obito, but Orochimaru and Madara not so much.
Guy kills Tobito
Sasuke and Orochimaru kill Madara.
Naruto, Bee, Kakashi, Sasuke, and Orochimaru take out the Ten Tails, with Orochimaru attempting to take its power. Naruto and Sasuke kill Orochimaru, one or both of them dying in the process.
