IDW has posted five pages from Transformers: Revenge of the Fallen Movie Adaptation #1 issue that will be out in comic stores starting May 20th. Unlike the novels, the comic adaptation doesn't need the same lead time so it is probably based on a more current version of the film script but not necessarily the final cut of the film. In a way the various adaptations provide an interesting look at how a film script evolves over time.
The pages can be found here and they do provide a few spoilers. It provides additional confirmation of the Ice Cream Truck being the Twins, suggests that Arcee is all three bikes that share a single mind, and that Stratosphere (who in the movie is probably just a plane, not a TF) has a role in the sense that he provides the air transportation to drop Optimus in position to take on Demolisher. Thanks to ghola-tleilaxu, Phil, and Gregory for the link.
