When I first heard that the pod emerged from the tumbler, i was like: "Youve gotta be kidding. But its looking more and more like this could be true. There are some clips on youtube of the chicago filming. If you watch these clips you can see Joker in his semi, adn the batmobile chasing after him. Sources have indicated that Joker is riding around in this semi, shooting an rpg. Sources also have us believe that Joker takes out the batmobile with his rpg. And, when you watch the trailer, we see the bat pod takes out the joker truck, and the final confrontation is between joker, and batman on his new ride. So, i would put my money on the fact that Joker blows up the batmobile, but no...wait a minute...he's still after me, on the bat pod. This will add to the notion of batman being somewhat ghost like. he can never die! because of his technology, of course!
