Baen has updated their publishing schedule at
http://www.baen.com/schedule.asp
"1635: The Papal Stakes" is scheduled for release in October 2012. I am hoping that this is the continuation to "The Canon Law", which was one of the more interesting ROF threads.
The are some "Kremlin Games" snippets on Eric Flint's website (
http://www.ericflint.net/), but I didn't see anything there for "The Papal Stakes"
