Just curious, but i've been wondering if the next book is still on schedule. Its been happening a lot these past couple years where my favorite authors have had to reschedule release dates. And no, i'm not just talking about you.
Traditional publishers tend to schedule publication up to two years away to ensure they make their target dates. But they have a LOT more to coordinate than do Independent Author/Publishers such as myself. They're coordinating developmental editing, copy editing, proofing, cover design, set-up, scheduling print runs, securing orders from bookstores, shipment to bookstores, arranging for advertising, sending early copies to book reviewers, scheduling publicity tours and signings, etc., etc, etc. If publishers complete all the steps early, they sit on the book until the release date.
I only have to write the book and perform the rewrites, work with my editor to get the book edited and proofed, work with an artist to have a cover made or make it myself, and then format the edited book into Mobi, ePub, and PDF versions and upload it online to the eBook sellers and print companies. If I complete the book early, I release it early. I use my experience to project a release date, and I admit that the date is sometimes a little optimistic. I also know that unexpected things happen to delay the publication. Last year my editor moved several states away from her previous address. That delayed the work a bit, but she and her people do such a great job that I was happy to wait until she returned to her editing. I also had a number of other publishing operations problems that took me away from writing while I worked them out. But I continue to establish dates that optimistically project a no-problem release because I don't know how to plan for unexpected problems.
At this point the schedule for AGU-11 is still on track for July 1, 2017, and I will do everything in my power to meet that date. Without adding half a year of time to cover unplanned contingencies, I can't guarantee any release date. So if you prefer, think of January 1, 2018 for publication of AGU-11 and then imagine how happy you'll be if it's available on July 1st, 2017.
