Thanks to Snakas and MillionHero for providing information on the Transformers Generations 2009 book, the third incarnation of this Japanese Transformers collectors book.
The new edition of the book, updated from the Transformers Generations Deluxe book, will contain more Transformers toys and images, including newer figures, will be available in three parts and offers a limited toy.
Previously the Secret Starscream and Gold Primus (God Primus and many sites incorrectly call the toy) were the prizes for the campaigns run in the previous two books.
The Transformers Generations Deluxe book is pretty hard to find now, and features artwork and concepts for many unreleased Generation One toys.
Volume one is due in February, volume 2 in April (at the Super-Festival) and the third and final volume is due in June.
