Okay, so because of the SDCC 2012 Fall of Cybertron Panel, we know that Peter Cullen, Nolan North and Gregg Berger were all in Prime as well. Two of these roles have been revealed (or were already known). Does this mean that the Spoiler Dinobots actually made the cut in S3? It'd make sense, since the Prime team did say the Dinobots were part of their plan, and since it's now obvious that the character budget was spent on the Insecticons, Shockwave, and Smokescreen, odds are the leftover budget was spent on perfecting quadrupedal characters. So, since the majority of this group is quadropedal, it makes sense that they'd be S3 to fight against Predaking.
