i think it that it'll end in mutual devastation blowing up rasenshuriken and like a amaterasu covered chidori but before that, Bee, hinata,kakashi,gaara, neji,lee,shikimaru,sakura,tsunade, ,choji,kiba,tenten konohamaru (if hes part of the war)along with A, onoki and Mei will arrive right before the final attacks and yell for them to stopa nd hell look over at them thumbs up,smile as he charges towards sasuke with their most ultimate attack, and it will end in both the death of naruto and sasuke, but this will be at the end of the war, as tobi will be waiting to see what happens, upon learning its over he will head to the battleground of the two, the allied shinobi forces will all be upset and as they go to pick up naruto and give him a burial (kakashi would grab sasuke because he knows naruto would want him to be given peace too, and cause hes his student.)tobi and his 6 paths appear, shinra tensei , blasting both naruto and sasuke out of reach of the shinobi forces, he will grab their bodies and use S/T again to leave and reveal that he will can revive the kyubbi by taking sasuke's EMS, at the same time it will show the last episode being naruto waking up with Jiraiya sitting against a tree writing, The Tale Of Uzumaki Naruto.
But before this the kyubbi will be extracted and he will master sage mode making him much stronger than before and sasuke will master sharingan and learn to be strategic again
