Few notes
-If that's the Doctor's TARDIS looks it's console room reverted to "factory settings" without her, instead of the crystal look. However this is probably temporary as the clapboard photo showed the crystal room for next season.
-The Daleks seem to be trying to pulling off the "Power of the Daleks" and "Victory of the Daleks" con again with somewhat more refined versions of the scrap/recon model. Also like Resolution looks like we'll see the caseless mutants do some mischief again.
-Noth's character is also back, as is of course Jack.
-Guessing this might focus a lot on the companions dealing with the Daleks on Earth while the Doctor tries to figure a way out of the prison. Then probably makes a big "You miss me?" entrance at the end.
-New Years Day.
