Transformers 3 Ultimate Prime with Trailer Toy

Thanks to images from IO9.com, we already know where Optimus Prime gets his jet pack as seen in the recent Super Bowl TV Spot. As the images of Ultimate Optimus Prime show, it is part of his trailer. I can't decide if I am a fan of "Butterfly Mode" (combined Prime with Trailer) but I am definitely intrigued by this toy. The figure is expected to hit toy shelves in August with a price of $79.99. The toy description from Hasbro:

Transformers Mechtech Ultimate Optimus Prime Action Figure
With the upcoming Transformers: Dark of the Moon movie, one of the most iconic characters in the Transformers lore will capture the spotlight as his heroic story becomes the focus of the first-ever 3D Transformers movie. Now, an action figure befitting such an icon will be available with the new Transformers Mechtech Ultimate Optimus Prime action figure. The figure includes the Autobot leader's classic trailer that doubles as a weapons arsenal and is an integral part of the figure's converting play pattern. The Mechtech Ultimate Optimus Prime figure features three modes of conversion – vehicle, robot, and robot with "mech suit." The trailer, which serves as a weapons depot and command center, also converts into a "mech suit" that Optimus Prime shows off when it's time to rumble. Featuring lights, launching projectiles, electronic battle sounds and Optimus Prime phrases, this is the must-have item for kids and fans alike.
