Holy shit it's finally done.
I will admit, I feared that Diana Gabaldon was going to George R Martin us, but she announced just a few hours ago on twitter that she has finally finished the ninth book of her Outlander series, Go Tell the Bee's That I'm Gone.
Now the real wait begins, because the rest is up to her publisher. Edits, prints ... I'm thinking the end of 2021, or early 2022.
Looks like I will need to reread and review the series to date. :)
