One Piece season 3 hasnt been confirmed yet, and while the news that it would be filmed back to back with season 2 has since been debunked, this would actually solve a major problem with Netflixs live-action adaptation of Eiichiro Odas manga. During an interview with Comicbook.com, One Piece Patty actor Brashaad Mayweather speculated about the future of the show, particularly the possibility of filming more than one season back to back. This led many to assume that One Piece had been renewed for season 3 already, which has since been confirmed not to be the case.
