I'd prefer if he ends it up to the end of the Akatsuki. And take a break.

Then I wouldn't mind after a year off or something, come back and write a kickass story again, but this time an older not so whiney irritating Naruto. A mature Naruto story. Probably called "The Hokage" or something and a story about not only Naruto but the leaf in general, the villages and world. And the protagonist is not on Naruto but on someone else, probably like Kakashi who is "The Hokage" and his vice apprentice Shikamaru.
