I think it's obvious in the future that Sasuke will play a role with Naruto, but I would prefer that Naruto would be the star, and Sasuke would be just some help. I don't really want them to be on equal ground. But it's kind of a possibility. Kishimoto could do something like that maybe. Well, we'll see.
Someone who's done despicable things get to share the limelight with Naruto? Yup, sounds just like Kishi's writing.
