I think August 2005 might be a little optimistic:
"I have been getting even more email asking if the latest publication date announced by one bookstore or another is correct. It isn't. I don't even care what date it is. I am still writing the book. Until it is done and delivered, all these announced pubdates are arrived at by throwing darts at a calendar. "

Heh. LiveJournal makes us forget to sign things.
