Given that they just created a new intro and ending that hints at the post time skip coming soonish, a lot of people were excited and thought that after this arc the filler would end. I personally dont think so. Basically, they can not use those intro/ending scenes after the time skip, and probably will have a brand new intro/ending scenes. So basically, I expect the fillers to end SOONISH but not as soon as everyone thought. My guess is we have another 3-4 arc's. Basically, as many episodes as a intro/ending scene usually entails.
