Very soon, with a little luck before the end of this year. I am currently halfway through the book, cleaning up spellchecks, rewriting passages and editing various ancestries and classes and then turning to the Bestiarium next, as that will be the bulk of the work. There were still remnants of the OGL Fiasco that I had to quickly implement back then before things were straightened out which also influenced the core Shadowdark Rulebook for a brief while.
