Re: How much farther does the rabbit hole go?
If Kishi wanted too, I'm sure there would be some ninja god still out there that created the ninjutsu world with rennegan that is the final villain vs Naruto. I really wish Kishi would end Naruto by killing off Madara and Pein, but my gut feeling is he is too noobish to achieve the one thing that makes this story worth watching: seeing achieve the rank of Hokage. I can see another story arc or two that puts him in his mid-twenties. I don't know how long the studio intends to make it. The story and episode count is epically long as it is.
