I had a flickthrough in a bookstore in the UK, and it's similar to the previous books: lots of the stock photos of the robots with small facts.
As it says on the cover this book is a guide to all three movies, so it has as many pages devoted to Blackout, Jazz and Devastator as it does to stuff in DOTM.
It sure is. Here's the review thread although it seems that few of us actually reviewed it at the timeIt's a similar (but not identical) story to the War for Cybertron game. Hasbro used to have the first few chapters for free on their website, but the link appears to be dead now. The sequel, Transformers: Exiles is up for preorder.
