Less news than I expected. Looks like Chibnall replacing Moffat will change the format and stories.

In addition to a new Doctor, the rest of the season will get a nice refresh. This will be Chibnall's first season as showrunner, as he takes over for longtime showrunner Steven Moffat. As such, Chibnall will add his own flair to the show and says now is the time for new fans to jump onboard as there will be "less old stuff returning, more new treats." In fact, longtime fans shouldn't expect the Daleks or monsters and villains from the past, and many episodes will be standalone stories that will be resolved within the hour.
But in the end, the panel was really about the importance of adding Whittaker and what it means not just for the series, but for the world moving forward.
"For me, the Doctor is pillar of hope, and striving for brightness and inclusion," Whittaker said.
