Voyager class Optimus Prime Gallery
From the moment Optimus Prime took Earth as a new home for himself and his people, he was rededicated to its protection. Since that day, he has focused all of his considerable will and power on rooting out the last few Decepticons and destroying them. To that end, he has upgraded and refined his sensor suite, and trained with Ironhide in tracking the evil robots.Voyager class Starscream Gallery
The moment his sensor net registered Megatron going offline, Starscream knew that battle was over and the Allspark lost. He converted to vehicle mode and boosted for outer space, hoping to buy enough time to rally the Decepticon survivors. Returning from Cybertron bearing the marks won during his reign over the Decepticon army, he is cocused on conquest. With a new army behind him, he has the strength to pursue his own goals, and perhaps, when the time is right, bring Megatron back.Bumblebee with Sam Gallery
Bumblebee and Sam were best friends almost from the moment they first met face to face. As they learned more about one another, that connection grew deeper and deeper. Now, whether Sam is behind the wheel, or standing side by side with his friend, they work together as a team. Against Bumblebee and his human friend, no Decepticon stands a chance.Transformers: RoTF Missile Mania Gallery
From Milton-Bradley, a two player game that involves knocking opponents players with toy missiles.
I think the most significant piece of information, is the image of Megatron that is on all the packaging either in the background behind the toy, on the Missile Mania box and the side of the packaging as multiple readers pointed out from the previous set.
Now the question is how you know that is Megatron? It is a case of following the pictures. Earlier in the year, CGI pictures of a tank with a head image appeared online. Later an action pose of a robot with claw hands and a face nearly identical to the previous pictures appeared online. A post that is almost identical to the toy packaging. Last we have images of Fast Action Megatron in his packaging (therefore official), that has a tank mode and a face mold nearly identical to the previous images. End conclusion is thanks to the toy, we have official confirmation that all are images of Megatron. Now does this mean he returns in the movie? Michael Bay said no to Empire Magazine but who knows at this point.
