I predict that naruto will use his shadow clones, use the jutsu to cut the ten tails to pieces (by pnj) and then will be extremely fatigued. At which point the ten tails will regenerate and will immediately counter attack naruto. Then Naruto has to rest to regenerate charka, but the shinobi army provides him a lot of support. Many will die. Then one or a few people from the K11 will die, which will make naruto extremely angry right before the Nine tails is recovered, and he enters the full tailed beast mode out of his anger. He will go up against the beast with the eight tails, and they will put up a much more solid fight, but will ultimately be defeated. Naruto is then caught by obito, who, before finishing him, decides to talk to him. Naruto convinces him that his plan is wrong (either by using the argument that he is being selfish, that everything will just be from his mind and nothing would be real, that he would be living only in a dream, or some other way), and Obito will try to seal madara, and get his ass kicked. he will then try to Kamui the Ten tails with kakashi's help, and either both of them or one of them is killed by madara. Naruto will be out of chakra, and by some series of events, which I am still trying to determine which will be more probable, Naruto will end up sealing the ten tails, not able to defeat, and maybe if obito is still alive he will create a second moon or something? idk, this ending is more guessy, but the beginning is what I see happening.
