It seems that Michael Bay just can't quit Linkin Park as the band seems to have been tapped to contribute a song and possible more for Transformers: Dark of the Moon. According to a source that wishes to remain anonymous, Bay chose "Burning In The Skies" from their current album A Thousand Suns for the movie's soundtrack. As a result instead of Burning as their next single it will now be "Iridescent".
While Linkin Park's involvement has not been officially confirmed, it would not be a surprising move considering the band's relationship with the franchise, previously releasing "What I've Done" for Transformers and "New Divide" for Transformers: Revenge of the Fallen. Chords from those singles were also incorporated into the score of the films. Chances are a music video is also in the works that will use Dark of the Moon footage and ideas. A sample of Burning In The Skies can be found at Amazon or full album samples here.
