If this was the case wouldn't it have been more logical for them to do Megatron since he turns into the ultimate therapod - a T-Rex ... which is also a distant ancestor of the bird. I would expect him to sell a little better than dinobot.
My daughter would be in heaven if they brought out an MP Silverbolt but I really think if they want to be balanced they need to bring out a Predacon to balance out the Maximals.
