TFW2005.com noticed an Amazon listing for a Transformers 3: The Dark of The Moon push-up board book. The listing appears to reveal the official plot of the upcoming sequel. Take a look at the plot description below:

"The Autobots Bumblebee, Ratchet, Ironhide and Sideswipe led by Optimus Prime, are back in action, taking on the evil Decepticons, who are determined to avenge their defeat in 2009's Transformers: Revenge of the Fallen. In this new movie, the Autobots and Decepticons become involved in a perilous space race between the U.S. and Russia, and once again human Sam Witwicky has to come to the aid of his robot friends. There's new characters too, including a new villain in the form of Shockwave, a longtime "Transformers" character who rules Cybertron while the Autobots and Decepticons battle it out on Earth."

Nothing has been confirmed by the studio at this time and we'll be sure to keep you posted with any and all Transformers 3: The Dark of The Moon updates as soon as we have more information.
