Just like with the first four movies, Hasbro in America have sent out their promo/sample box to select media outlets in the US, which includes the owners of some of the major Transformers fansites.

Usually they don't have anything exclusive in them, as they are just a sampling of first wave toys for media outlets to review and promote, if they want to... but the packaging (and it is HUGE), is probably the most interesting thing about these, as they would look great sitting in the display of a fan's movie toy collection.
