The Character Operations Manual will be released soon, and I hope they got you an advance copy and you guys can get to adding the book ASAP.
Some blogs have been talking about exciting stuff!

They are adding "Alternate Class Features" for many of these classes, which are not Starfinder "Archetypes", but are much closer to Archetypes from PF1. It also includes a bunch of new class options.

Modifications for all 13 races in the Starfinder CRB, including the legacy races! Ability score and racial trait options unique to each species! New feats, gear, spell, and class options, and if your character has the right physiology, you can take these options no matter your race.
And of course the 3 new classes, and a bunch of stuff from streams!
Just wanted to give you a heads up!
