Those who think that the fights are not over really don't understand anything about Oda's writing.
Can't you see that the end of the arc is coming? Each chapter concludes a secondary fight, page one, ulti, who's who and now sasaki.
It's clear in the structure though, it's like dressrosa. In less than 10 chapters it will be the final fight of the arc and in less than 2 volumes the end of the arc or at least the end of the raid. Wano will end very quickly
