According to this article from 411mania.com Warner Brothers will be unveiling the new Batmobile at the next Licensing International Expo.

Rumor has it that the next film involves “arial assaults”. Could this possibly be referring to Batman dealing with an Arkham breakout? Considering that Batman is now a fallen hero and the pariah of Gotham, he’ll need to be sneakier when dealing with criminals and perhaps this means dealing with them from a super stealthy aircraft.

The Batpod was released at the 2007 Licensing International Expo, a year before The Dark Knight was released.

If this is indeed true, I am excited to see what a batplane in the Nolanverse would look like. Everything thus far has been grounded in realism so it’ll be neat to see how they’ll tackle a batplane. Considering that with each movie we’ve had a new means of transportation for Mr. Wayne’s alter ego, I have a feeling that this rumor may turn out to be truth.

For now, we’ll just have to wait and see.
