i've been think about how the end is going to go down and i'd like to hear some ppls opinions on it so here's mine:
" in the final battle between sasuke and naruto its going to happen like this: fighting and fighting to the point where they pull out their top massive attack and at the end like how naruto was smiling when he lost in their first major fight, i think sasuke smiled or is smiling as his eye's power consumes him and the only thing left of him is his clan's tag and eventually naruto brings it back to the village which then he'll say something like "i promised you i;d bring you back " as sasuke dies Madara is standing above them somehow maybe a cliff or something, when naruto is bending over sasuke, he begins tearing blood, then flashback to when Itachi was speaking with naruto and then sends a raven into him and says something about given him a power then hoping he'll never have to use it. back to present , slowly naruto looks up and his eyes have changed into rinnegan. Madara looks at naruto with a smirk and starts saying something like that crafty itachi and explaining the origin/ creation of the rinnegan going into a flashback of when he gave Nagato his rinnegan." this is just me though
I would love that kind of ending but I don't think so. I thing they would make it so the kyubi would give naruto and sasuke half of his power and they will make sure to keep the world safe from every evil that would come or something like this :/ But the battle will be epic.
