You can see the pics in the link below. The pictures don’t show any of the new robots (and neither do first posters) but the following, I think, is more valuable:

USA Today also points out the new robots that will invade the film. They are “Decepticons Soundwave, a fearsome communications expert, and Devastator, whose arms and legs are built out of other Transformers. And on the Autobots’ side is Jetfire, a villain whose age and broken-down physicality leads him to help the Autobots.” 

At least we know now who Bay was referring to as the geriatric robot. The Transformers: Revenge of the Fallen is expected to play in theaters June 26, 2009.
