3rd Logo (March 2, 2012)
Logo: On a black background, we see the same logo from before, but 2D, solid and in white. The company's name has a slightly different font compared to the previous logo. It slowly zooms forward.

Variant: On the trailer for Project X, the logo appears on the same dirty green background as the Warner Bros. Pictures and Silver Pictures variants and also has stains.
