Well after looking through this new reference material it really has nothing insightful to offer. I was hoping to see more in regards to transformation mechanisms, but it is mostly a few new tidbits, such as: the seats (new versions?), six-types of vernier thrusters, and that's about it.
I'm pretty meh about the whole book.
Also, a lot of the (revised) reference material looks as though it is only based off the Hasegawa offerings. There are no real cues of the older reference material.
Definitive? Highly unlikely.
