1) Naruto will end up being Hokage after this war.
2) Sasuke will regroup with Taka/orochimaru to find the guy who knows all + use that info in scroll.
TIME SKIP
3) Sasuke attacks Konoha (with or without Oro)
4) Naruto either draws or dies against Sasuke
possible endings :
1) Sasuke will regret he killed Naruto and wanders the world for the rest of his life in regret.
2) Sasuke and Naruto both die in Chidori/rasengan clash ..
3) Sasuke and Naruto fight till the end and draw (without any of them dieing) Naruto stays hokage while Sasuke wanders the world after finding peace..
-> IF Naruto should die, then we'll find out he got a child with Hinata during the time skip

so his legacy will go on !
(just my idea) xDDD
