After a brief period where it was unclear, it looks like Star Wars and Marvel will be going to Disney’s streaming service after all. Presumably this won’t apply to Marvel’s series that were co-produced with Netflix before Disney decided to create their own service, but future projects will likely debut there.
Disney’s streaming service is expected to debut in 2019. New releases through 2018 (which include The Last Jedi and the upcoming Han Solo standalone) will probably still debut on Netflix due to Disney’s shortened contract.
