I really hope this story continues into the Dressrosa arc since I'm interested in seeing how the characters react to Doflamingo's disclosures regarding his past. But I have a feeling that this tale is about to come to an end, same as Naruto, which never disclosed the characters' reactions to the Otsutsuki clan since the bulk of the stories concentrated on romance, adventure, and slice-of-life rather than the reactions of the audience to the comic.
