My sister just got the MK, Epcot, and DAK editions of the Imagineering books for Christmas. My mom and I searched for the HS one so that we'd be able to complete the collection for her, and found out that it is not scheduled to be released until July of this year. I would have assumed there was an older edition of the book for when the park was still MGM, but I guess not? Anyway, I finished reading the first three and loved them. I plan on pre-ordering the HS edition and having it to give to my sister for her birthday.
