Have been lowkey expecting this announcement since "Jodie is leaving after some 2022 specials" has been rumored for a few weeks... but very surprised that they just dropped this on twitter out of nowhere rather than announcing it at the hyped Comic Con panel they had four days ago.

I would've liked to see more of Jodie, but the most likely scenario was always gonna be Chibnall outlasting her rather than the other way around, so I'm content with this news. I just hope they make good use of the time they have left.
