Found inside the newly released Calvin Johnson Megatron shoe/toy combo, is a little bonus card alerting the buyer to big Transformers news at "The Game" which is most likely to be their annual Superbowl on February 2nd... and also expected to be a trailer for TF4.

The timing is about right, as I think some previous Transformers movies did the same. But I think we should still see some teasers in theatres before then, as we usually get Teaser Trailers around December before the release of the Movie.
