Great question!
So my initial plan is to do a chapter-by-chapter of Fire and Blood, although it’ll probably be in bullet point form similar to what I did with WOIAF.
Then, I was planning to do an update on some of my essay series, similar to how I wrote a followup essay about “Hollow Crowns and Deadly Thrones” after WOIAF.
At the moment, I don’t have any definite plans for which essay series to revisit: obviously, the “Hollow Crowns” series is most likely, but whether I’ll do the “Hands of the King” or “Laboratory of Politics” depends on what kind of material there is in Fire & Blood Volume 1.
