Deluxe Autobots Not to be in Season 2?!

We've received an anonymous tip that the upcoming Transformers Autobot Deluxe Cars Roadbuster and Whirl will not be featured in the upcoming Season 2 of Transformers.  Theories state that Whirl was dropped in order for Skyfire to be the only flying Autobot.  Roadbuster was also removed due to being considered too violent for American television.  Whether this rumor is true or not, has yet to be confirmed.
