Well IMO if Naruto were to be the Hokage then there would have to be a third skip. Plus, they could show Sakura being stronger than Tsunade as a follow up to her training. And if that would happen, that would mean Sasuske wouldn't be in Konoha or would be dead because in the 1st data book it says Sakura is strong, but is too distracted by Sasuke. 2nd book says she is stronger because her mind is off Sasuke. 3rd book says she just is looking more of sasuke than a friend and her admiration for Naruto has grown. If Sasuke were to come back, she would be annoying and useless like in the beginnning of the series I guess.
