With just on two months left to release, Bay has shown his rough cut to Spielberg, and he loved it.

They are still pushing to make sure it is fully finished by the due date, but the full trailer is done and ready for release on May 1st with the Wolverine Movie. Not sure if that will apply here, but I think the relationship between the two movies (Paramount and Hasbro), should give it good odds on them being paired here as well.
