A new image posted on the Planet Iacon Facebook page by Seibertron seems to reveal the fate of some of the characters from Transformers: Dark of the Moon. The source of the image is unknown so usual validity caveats but it does match the propaganda posters seen on sets during filming and might clarify certain story beats that have been hinted at by alternate vehicles modes. The image is after the break.
Update: As pointed out in the comments and elsewhere, the image was created by TFW2005's TunaKaan's photo-shop ninja skills that was responsible for other TF4 related art. May be fake, but still cool looking.
