Kevin Feige and the rest of them at Marvel Studios are a crafty bunch.  Since the first trailer from The Avengers: Age Of Ultron was leaked prematurely it appears that that they just decided to let us see it.

And it’s fitting that the first trailer for Ant-Man is only slightly larger than an ant.  The full-sized version will be aired January 6, during the premiere of Marvel’s Agent Carter.

What an awesome idea!  Such innovative marketing is another reason that Marvel Studios is heads and shoulders above the Distinguished Competition!
