How do you download sideswipe in transformers revenge of the fallen

Thus far, Sideswipe has not been released yet. He, a full version of the Original Starscream, and other content is supposed to be downloadable for the PS3, 360 and presumably PC versions of the Revenge of the Fallen Game late this summer. Otherwise there are no other ways to get Sideswipe or the Original G1 Starscream. I'm sure some hackers will find a way, everyone has a weakness.
