Even if Sarada takes the Hokage seat (it's unlikely she won't at some point) it will still link to the previous generation. She is the daughter of the student of the fifth Hokage and the team mate of the seventh Hokage. Also if Konohamaru takes the Hokage spot before her, she will be the student of the eighth Hokage. But it's debatable if we will actually see the Hokage get changed in the series, considering that right now, Naruto is the Hokage. Unless Naruto gets killed (which obviously was hinted that way) he won't be dropping the Hokage spot anytime soon. Oonoki was almost eighty years old in part 2, and was still the Kage. Considering Naruto life-force as an Uzumaki, the fact that he's a reincarnation, his absurd quantity of chakra and the SPSM/SP chakra, he could push his Hokage role way beyond Oonoki did. So unless Naruto gets killed or gets dethroned by the Village for some reason, i don't see the change happening too soon.
