according to the
publisher site, this book will be released the december 26,2014.
I wonder why this book delayed so much. I'm in the same situation as yours having passed the OCA this month, I wanted to get the new Sierra book but when I saw it was already saying the release date would be in december, only I don't remember being only in 2014... now I have already ordered Ganesh book from Amazon and I'm only waiting for them to deliver.
