Seibertron's got a report of the second volume of the Transformers Generations book due for release at the end of this month.

They've got a image from a backup comic strip in the book, with the 80s style Marvel colouring seen recently and discussed in this thread, but you can also see it, and other sample pages on the Book's website

The cover shows a certain Autobot spaceship (well it was in the Japanese cartoon) and one of the sample pages has what looks like a prototype of that same big toy, perhaps as a counterpoint to the new Autobot spaceship toy. Perhaps it's the featured toy in the "Maniax" section. Perhaps it's a hint of something yet to be revealed? (Probably not)
