So, Jodie Whittaker's last story tonight, in the Centenary special, Power Of The Doctor. I'm surprised I have't seen leaks from the press premiere abound, other than that apparently they didn't show the regeneration outcome, just a caption,
My predictions: It'll be more an anniversary show than a 13th Doctor wrap-up, and the eponymous power of the Doctor will be the Timeless Child's magical infinite regenerations nature, and will be sacrificed to save the day, leaving the Doctor with a regular or mystery number of remaining regenerations, and never be mentioned again. (Because it by definition means there's never a possible threat to the Doctor's life so long as it's still there.)
