That's the thing... IF they did so AND those changes are in service of the GM's needs rather than the desires of players who want more power then they should have been excited to talk at length about them and give previews of the text similar to the kinds they made for the phb. Instead we got Krenek gushing with excitement about using them as a player with some new PC and Perkins reminding him of all the things not asked or talked about. I'd love for them to be more than busy work to justify busy work & "MOAR POWAH!", but the threadbare reveal in a video supposedly showcasing it is concerning in ways that do not fill those sails with hope.
