We may get a 30-50 chapter arc next I imagine consisting of small timeskips and visits of different islands Elbaf/Roadstar being among them, Law and Kidd strengthening their crews and territory/manpower, find the location of the last road poneglyph
Basically named Road to Laughtale arc
Then Laughtale after that as the final arc could work, which would then encompass different islands with the war.
