This trailer is made by MTV. Here is some comments from their website:

If there’s one thing director Michael Bay brings to the table, it’s often jaw-dropping action scenes. Now — thanks to an exclusive “Transformers: Revenge of the Fallen” featurette from tonight’s episode of “Spoilers” — we known our second visit with the Autobots and Decepticons will be anything but a quiet affair.

Showcasing the film’s worldwide shooting locations, we’re able to observe for the first time just what will transpire at the college of Shia LaBeouf’s Sam Witwicky (hint: it’ll be loud). We also see Megan Fox and Josh Duhamel both in character and talking about their director, along with LaBeouf, and a ton of explosions and stunts.
