Well, I just heard back from Anne Groell, Lynch's US editor, and you can forget about the summer 2009 publication date. Scott Lynch has yet to turn in the final manuscript, so it's impossible to schedule the novel until the ms is turned in.
Fall 2009 remains a possibility, but it looks as though the third installment in The Gentleman Bastard sequence will not see the light until 2010. . .
Bummer. . .
