That's a misleading thread title. As a Variety article explains, Disney+ will not be funding new episodes of the main show, but they're a partner in a spinoff:
“We’d like to thank Disney+ for being terrific global partners and collaborators over the past two seasons, and for the upcoming ‘The War Between the Land and the Sea,'” Lindsay Salt, director of drama at the BBC, said in a statement...“The War Between the Land and the Sea,” a “Doctor Who” spinoff starring Russell Tovey and Gugu Mbatha-Raw, is due on Disney+ as well as BBC One and BBC iPlayer later this year.
I mean, the title is correct, Disney is done making Doctor Who. There is the spinoff yet to air, but that is already filmed. There is no Doctor Who in production as of now, and once the BBC starts back up with the Christmas special for next year, Disney isn't going to be involved. What I'm really interested in is where international viewers will be able to watch going forward. I assume Disney isn't going to let another streamer have their produced eps, but I hope whoever is going to air the new episodes will also get the revival back catalogue to 2005. I think not having old eps to watch really hurt the show on Disney+. I know the rights were held by other steamers at that point, but it really soured the experience for me as an American fan of the show. I only started watching when I got BBC America in 2009, and if they hadn't been rerunning all the old eps for me to get into, I might not have bothered with the show.
