Ok, thanks Kishi for re-writing the manga.You have no idea how the seal works, or how the Biju work. The seal is GONE.I'm still waiting for a page that shows Madara and Obito were using "Rikudou Sage Mode."
Undoing the seal is the same as opening the seal, hence why he needs a "key" to do so. The seal isn't gone. If the seal was gone, nothing would be keeping Kurama in his body, and the stomach marking would be gone. I've already proven Naruto has the seal still, blather to someone else.
I'm trying to say Naruto still has his seal intact, it's just "open" at the moment, and there's the possibility that Sasuke can lock away Kurama and the other chakras into the seal. The question is, can Sasuke implement a new lock or will it just be the same lock Naruto can undo?
