Some things that I noticed

1. The prison looks very much less like Shada with these new shots, I think we can rule that theory out.

2. The Fam looks to be in Jo Martin’s TARDIS in several shots, hopefully we’ll see her return.

3. Jack makes it to Earth/Starts on Earth and is with the Fam.

4. The Trump parody character and a man who looks like the villain from Spyfall appear.

5. Their plan seems to be weaponizing the Daleks for some purpose, similar to Victory.

6. This also makes it look like the Dalek plot is running mostly independently to the Doctor’s

7. No apparent shots of any of the companions in great peril, which doesn’t necessarily mean some, one, or all of them won’t leave

8. Not much Doctor. Possibly a Doctor light story?

9. New Dalek design, attacking Earth. Similar vibes to The Stolen Earth and Journey’s End.

10. No obvious clues to hint at mention of the Timeless Child or the appearance of The Master.

11. Didn’t see any Judoon or Gat, so I don’t know if they’re carrying on with the plot lines of their appearance at the end of The Timeless Children.

I think that mostly covers my observations. Anybody else see stuff that I didn’t?
