well i think its going to be a while because of all the storylines that have been introduced and all the side stories to come. Like Naruto becoming Hokage, Sasuke and Itachi, Sakura being with someone, the 4th, Orchi and his arms, the Orginazation Itachi is in, Kakashi's story, hell there is just so much more to be shown I think it will go for a well 200 if not more episodes. Something like InuYasha or One Piece.
