I e-mailed the IDW store concerning the availability of this book and in a reply e-mail was told they would be "putting it up for sale on our online store this week". So sounds like there wasn't a sellout at SDCC and there is still a chance for us malingerers. 

Just an update that this book is available for purchasing on the IDW website NOW
