Just because the overall celebration of TNG's 25th occurred - at least for the convention circuit - during 2012, doesn't mean we can't experience an ongoing celebration
through September of 2013. IMO, this book isn't unwelcome.
Regarding the CD, I agree the publisher could have gone further with a DVD for a virtual tour. However, my understanding of the product description is that the focus is the book itself. Old school? Maybe. But this style of book would never, IMO, be enjoyed on a Kindle.
