Now that you've mentioned it I can see the similarities. I actually did like that there were Predacon, Decepticon and Autobot factions in RID. So far we have a small team of Autobots who will probably serve as our eyes into the ancient Predacon/Maximal conflict which will be interrupted by Terrorcons as the big bad. Predacons will probably land in a comic relief/support role at some point in the movie. It will keep them away from the big fight and well enough for the next movie. I can see Decepticons making an appearance as a presence behind the scene. I don't think that Scrouge and Terrorcons will make it out alive. I am hoping for a cameo appearance. Caple said that they traveled through time and space and it really makes them sound ancient. Did they hint how big are they going to be? I assume bigger than average animals, but smaller than King Kong?
