Not a lot of news in the new DWM, as they're in the between series period. Location scouting is happening and the non-RTD writers are at work on various drafts of their scripts.
The first and last Specials are broadcast ready but not the mysterious second one. (Lots of effects work?)
The novelisations will include lots of extra material, particularly for the Nobles. (So hopefully including the scenes they weren't able to shoot with Bernard due to his health.)
Bonnie was asked to return by Russell before she was asked to appear in POTD by Chibnall. Which only makes me more convinced that she's in the Specials as well.
