Is there going to be another Campaign book to go with PF 2.0?
I admit I probably wouldn't buy an update on the Inner Sea World Guide, unless it was some sort of double-sized beast. Most everything in the one we have already is setting neutral, and advancing the timeline is to me not worth the cost of buying a new book
a 'companion' book with timeline updates and errata for Inner Sea Guide subjects and entries for nations outside the Inner Sea would be interesting.
