Seibertron.com member enclinedesigns shared with us the following, small, yet intriguing image. The image is of Botcon Animated Motormaster's alt-mode equipped with a blacked-out trailer.



He also tells us that the trailer will be able to combine with the Animated Stunticons to form a combined form of about 12 - 14 inches in hight.

However, there is no confirmation of this actually coming out yet, but it does look awfully familiar to the original teaser images of the upcoming Make Toys RTS G2 Optimus Prime trailer.
What ever it is, we'll keep you updated!
