I think that its most likey that the story will go all the way to the end of where the Atakasuki are destroyed. Sasuke dies saving Naruto. Naruto completely supress's the fox inside him. Hinata finally gets enough guts to tell Naruto she loves him. Ino and Choji get married...just kidding. Kabuto and Orochimaru completely merge and he looks like a combo of both of them, like Oro's white skin and eyes and Kabuto's hair and glasses, but he has split personalities. Naruto eventually fights him.
Once all the loose ends are tied up we have a time skip to Naruto as Hokage and completely bored with having to be more an administrater than a fighter. And he either marries Sakura or Hinata and they already have a child who wants to become Hokage someday. In which this is were they end the series.
