The trailer is light on content, but it's just long enough to let you know that the Beast is coming.

The Beast was teased at the end of the original inFamous, when Cole had a vision of the forceful entity that only he can stop. At the start of inFamous 2, Cole fails to destroy the Beast, and heads to New Marais to prepare for a second encounter with the evil being while his hometown, Empire City, is burned to the ground.

If there's one thing you can assume from this trailer, it's that the Beast is huge.
