Its just a pathetic idea to think that Sasuke is going to be Hokage. As Itachi said:''Beeing Hokage doenst make everyone accept you.If everyone accepts you you'll become Hokage''. Sasuke doesnt care about the opinions of other people he wants to become Hokage through power not ''love''.
I think Sasuke will never be equal to Naruto . I mean Naruto Sage Mode was stronger then Sasuke MS. Naruto KCM is also stronger then Sasuke EMS i think which means that Naruto BM is far stronger then Sasuke EMS.
I had this theory a long time ago while reading DB . Could it be possible that Naruto has to die to get stronger like in DB ?
Maybe he is going to meet the Rikudo in the world of the dead and he gives Naruto new power or something like that.
