The guide was finished in July and is accurate for version 1.45.
That was too late for a book to be made about it. In my opinion having a guide in printed form of a version shortly after release, would have been useless, due to the many changes.
Then again, July was too late to create a printed version, especially with everybody on hollidays. So in late august, Lynn contacted the parties that might be interested in the guide and the only thing that could be done was giving it to the magazines too put on their CD/DVD.
That is what is happening now.
