I predict that Tsunade will resume the role as hokage. Some say she may have died but I predict that she and other kages will probably join the final battle as well. I have no doubt that Kishi will make this the Ultimate Showdown to end the series. It is obvious to say that Naruto is the runner-up for the title of Hokage but in my opinion, I don't think he would immediately take that position just yet. Therefore, I think the series wiil end without the appointing of a new hokage, but we can expect that naruto will become hokage even if the series ended. But my predictions are just my predictions....Kishi will do whatever he wants. I wouldn't be surprise at all if a sixth hokage is appointed. I also wouldn't be surprised if Sasuke becomes the first Uchiha Hokage......
