I believe that perhaps naruto will die in front of the entire allied ninja forces and save the world and this will bring the other nations together in light of the catastrophe and naruto's heroic efforts. The prophery said he would greatly change the ninja world and perhaps his life and death will teach the world and HIS ninja way is accepted. It's a truer ending, unlike the soppy ending you typically get. But hey, maybe he lives and survives the final battle and becomes the leader of the "Allied Shinobi Nation" and becomes Hokage. Also I think people forget in light of Naruto's amazing feats, that he's still a GENHNIN!!!!!!!!
