However, Mark and I were able to proceed a tad ahead of schedule, meaning the Cookbook is now slated for release in August:
That's right; scheduled for release this month. Five months ahead of schedule. Don't worry though, the quality is as high, if not higher, than previous versions as this book is a genuine collaboration between Mark and I. By splitting the work in this way, we were each able to focus on particular areas in which we had strengths.
We also received good feedback, to guide improvements, from fellow MVPS Leslie Vail and Jivtesh Singh.
You can pre-order the book from Packt Publishing, and very soon your pre-orders will be shipped. From what I gather the book should be available to order, as opposed to pre-order, in the next week or so, so you won't need to wait long to receive your copy.
