I dunno. At the end of chapter 700, something is said about "volume 72 on sale in feb. Then, next spring...!!!" So, I'm imagining another Kishimoto project in the spring. Whether that has anything at all to do with Naruto, I couldn't tell you. I don't know why, but I'd give a follow up series another shot. It would be just that though, it would get a shot, not loyalty.
