Prediction: madara still has the upper hand, alot of people die(kakashi, gai, and bee is hurt real bad), and naruto looks back at all of it. he gives a speech and stuff. sasuke comes and the 9tails finally recovers his chakra. naruto and sasuke tag team the 10tails and own. they run out of chakra, but obito and madara are still in the fight.
i got two different theories from here:
1) obito realizes he was wrong and fights madara. madara kicks his ass and leaves him on the ground near death. with all the ninja and samurai in one whole area almost gone, madara uses that meteor jutsu one last time. madara gets cocky and says something like "if you can survive this ill give up." they survive it, but doesnt hold his end of the deal. orichimaru shows up and unleashes some snake/dragon summoning jutsu
2) they continue with their moon jutsu, but find the 10tails doesnt have enough chakra. everyone charges and they win all taijutsu(you can tell i didnt put much effort on this one)
