I think the last battle is in Naruto Shippuuden Movie 2 but they don't really fight though.

I hope sasuke will win....but if he wins....naruto will die right? if naurto dies....the show won't be calling 'Naurto' anymore....-____________-IIII

they wont

..... Well as much as I would love to see them fight (and sasuke die) I'm sure they will end it where they don't and just live happily ever after

IF they do fight, Naruto will win. He has too. That's the main reason for the show now so if he dies, then what? What will become of the show? So no way will they make Naruto lose to Sasuke. If they do fight, in the worse case scenerio is that they end in a draw. Boy, that would be one bloody battle...I kinda want to see it if it does happen and i kinda don't

If they each other then I think it will be Naruto..

none they will both die

We can't tell the ending cause we dont know naruto last for how long . It could be maybe 4 years , 8 years , 12 years, and 20 years too

if they fight i think sasuke will win n then hand naruto over to akatsuki

naruto then die soon after

If they fight, obviously Naruto will win, it IS the name of the show ^^

think of it this way: naruto has the entire title of the show defending him.

yh but it doesnt really mean he'll win anything can happen in naruto if he dont win it will make it more excitin like my idea naruto loses to sasuke gets taken to akatsuki n then a big operation goes off when the village of the leaf go on a rescue mission to get him bk before they take the fox out if him to me storyline like that sounds uber immense

My friend once told me that at the end of their fight,both of them die...
Well,I don't know if my friend told me the truth or not because that time I don't really like Naruto...

naruto duh isnt it ovious his the protagonist if he dies naruto or naruto shippuden will be an epic failure
