I'm guessing we are going to see a Naruto->Shippuden style of wait, they are wayyyy to close to the Manga. I'm not sure how long they can stretch this "I might lose my powers anytime I do anything" bit, but I think they will figure out something to keep the filler going for a while.
I'd love if they did that so I can come back to the show in a year and a half and not have to worry about random fillers in every arc, it worked well for Naruto imo.
