You guys get out the pitchforks now, but then you'll jump on the bandwagon of [insert line] once it starts up
As for the Bumblebee namedrop, it's probably just that - a namedrop of a well-known "character type" and trademark. From everything I've heard, War for Cybertron is a prequel to TF Prime, what with the similar "a new Autobot leader steps up in their darkest hour" storylines.
I don't see what all the complaining about Bumblebee's exposure is about, just deal with the fact you're just along for the ride in Transformers. Besides, he wasn't the primary character of Animated and barely appeared in Revenge of the Fallen, so are you really miffed about his role in Transformers marketing now rather than his (so far, average screen time) appearances in media?
