There will be an update to the Players Guide probably within the next month (definitely before the one day) - it will largely focus on adding major events from the last year (civil war, anyone?) and extended write-ups for each of the nations of Terna.
There will be updates to a couple race packets but we're not going through every single one. I think the one that will see the most changes is the High Ogre packet, and to my knowledge we've never had any High Ogre PCs at Chicago (correct me if I'm wrong!)
I'll let Rob or Ryan cover maps, I'm not sure of the exact timeline on those. They are being worked on, though.
