I decided to make a part two because part 1 of my theory only covered the last battle and not what I think will happen at the end of the manga and didn't exactly go into detail of the last battle. So here is the second part of my theory! Really interesting! 
Check out Part 1 of my theory before taking a look at this one:
The Third Prediction: Continuing from the second prediction, the final battle between Naruto and Madara determining who becomes the Ten-Tails Jinchuriki. Naruto and Madara are fighting on top of the Ten-Tails and Naruto goes into fully powered Kuruma mode and Madara activates his final Susanoo. Madara declares to Naruto it is fruitless to try and stop him and says "I got inside you once and used you as a puppet!! And I can do it again just as easily as before!!! I will become the Juubi's Jinchuriki and perform Eternal Tsukuyomi and make a world where there are no losers!! Think about that Naruto! I will make a world where you will be Hokage, a world where everyone will love and adore you! A world where your parents are alive! Today is the day they died afterall! What do you say..Naruto!?" Naruto then fires a giant tailed beast ball and yells to Madara "I now have Yin and Yang Kuruma inside me, and there is no way in hell that you are going to manipulate me ever again! And I don't give to shits about your Genjutsu because it ain't gonna happen on my watch! As much as I would like to see my parents alive, I would rather see them alive in the real world and not a fake world! Besides, my dad is already here right beside me on the battlefield! And I am not going to dissapoint him! I won't let any of my comrades down! Today is my birthday after all and I would like nothing more than to see you stopped! With that being said, this is also the day that you die a second time!! Brace yourself Madara! Your time has come again!!!" Both Madara and Naruto are heard from across the battlefield by the entire Shinobi Alliance and Orochimauru and his subordinates as well as Kushina, who surprisingly was ressurected by the Rinne Tensei jutsu that Madara had performed on himself and consequently everyone else. Minato, the Hokages, the Rookie Nine as well as the Five Kage immediatly go over to confront Orochimauru and question him on regards to why he has appeared on the battlefield and how and why has Kushina been ressurected. Tsunade comes to Orochimauru's aid by telling everyone to calm down and explains everything to them, but she and Minato ultimately confront Orochimauru as well on Kushina ressurection and Orochimauru states "I overheard everything that Naruto and Obito were saying. Since I have changed my ways and had a spare Zetzu left, I decided to have Kushina ressurrected with the Edo Tensei jutsu as a birthday present to Naruto. It was the least I could do after all of the trouble I put him through with Sasuke and his team. I however did not expect her to completely come back to life! I see that Minato has also been fully ressurrected? Did someone use the Rinne Tensei Jutsu on everybody?" Tsunade and the Hokages tell Orochimauru and Kushina that it was all Madara's doing in attempt to become the Ten-Tails Jinchuriki and he consequently revived everyone else around him. Kushina then sees Naruto battling Madara all by himself across the battlefield. Meanwhile, Naruto is struggling against Madara's final Susanoo and is on the verge of defeat when Madara pins him down with his Susanoo and a Wood Dragon. Madara then yells to Naruto "Poor miserable brat! No mother, no father, no friends! All of them are dead! All alone now!! Allow me to make this final blow quick and painless. I will make sure that you will be alive again along with everyone else inside my ultimate Genjutsu!" Naruto screatches to Madara "I told you once before! I don't give a shit about you fake world! I also wouldn't count on me dying just yet!" Madara replies saying "How can you have such strong will when you are all alone now!? everyone precious to you is either dead or slowly dying in front of you?" Naruto then says "You should really take a look around you ya'know! Your Rinne Tensei did not just work on you!" Madara shockingly replies saying "WHAT!!?? WHAT DO YOU MEAN!??" Then Madara takes a look across the battlefield only to see all of the Shinobi Alliance resurrected by the Rinne Tensei Jutsu with Naruto's resurrected parents, Sakura and the Hokages yelling "THAT'S RIGHT MADARA!! HE IS NOT ALONE!!! HE HAS ALL OF US ALIVE AND WELL BY HIS SIDE!" Madara then proceeds to go all out trying to crush the alliance, but to no avail. Madara then gets overwhelmed by the alliance and with the finishing blow coming from Sasuke, Hashirama and Naruto! Naruto then yells "This time you won't come back! RASENGAN!" Sasuke yells "You are a disgrace to our clan! CHIDORI!!" and Hashirama yells "You dissapoint me old friend! Wood Release: Tree Bind Flourishing Burial!!!" Madara is finally defeated and Naruto decides to seal the Juubi within himself and gains a staff similar to the one Obito had earlier. The entire shinobi alliance come to congratulate the three of them. To Naruto's shock, he sees not only the entire Shinobi Alliance alive, but his mother as well. Orochimauru then comes to Naruto and explains that he was the one who brought her back to life with the Edo Tensei Jutsu as a birthday gift to Naruto and for all of the trouble he put him through with Sasuke, but had no intention on reviving her completely. Naruto then rushes over to his parents who are overjoyed at seeing Naruto as well. Fast forward ten years later, all of the Shinobi Nations have become one nation with the capital being Konoha. Konoha is much larger in size and stretches for miles and is nick-named "Shinobi City". The former Hokages are always seen overlooking the village and are proud to see how the world turned out to be. Peace is brought to the world, Naruto is the new Hokage as well as the new Sage of the Six Paths and Sakura is his wife and they both have 2 children together. Sasuke is Naruto's right hand man and is married to Karin. Hinata found a love of her own. Shikimauru became the Daimyo of the new Shinobi Nation. Orochimauru is now dead and the rest of the rookie nine are now part of the new Konoha high council. Fast foward another 60 years, Naruto is an old man on the verge of death. Just like how the Sage of the Six Paths had to chose a successor, so did Naruto. This time, Naruto would not make the same mistake he did in his previous life and decides to chose both of his sons as his successor, maintaining the peace he brought to the world and ensuring that another conflict would not erupt from his choices. Naruto then says his last words "I never would have imagined that it would end quite like this. Now I can finally join everyone else in the afterlife without worrying about a future conflict being sparked by my two sons...My time here in this world is up. I have nothing more to offer it.." and then dies on his deathbed. The End
