What does Catwoman on the Batpod have in common with three tumblers, a massive military vehicle and the Batwing? They’re all chasing each-other through narrow city streets in these new videos taken from the set of The Dark Knight Rises in Pittsburgh.

First on the list are videos courtesy of youtube users Miclarko and westsidetriad. They feature three tumblers escorting a large black military vehicle down the street followed by Catwoman on the Batpod.

So this video basically confirms our theory that we will see three of the prototype tumblers at the same time. Like we mentioned above, they seem to be protecting the truck that Batman appears to be chasing in these videos.

Does this mean that Bane has gained access to the blueprints of the tumbler and is using them for his own protection? Of course this is just speculation, but it seems to make sense based on what we have seen.

This video below features a tumbler being closely followed by the large black military truck. Two more tumblers then join from around the corner. Since the camera truck is absent and there appears to be a helicopter camera capturing the whole thing, it can be confirmed that we will see two tumblers abruptly turning the corner to give chase to the military vehicle (or escort it) in the final cut of the film.

More video has also cropped up of the (temporarily named) Batwing as it cruises in a rehearsal run down city streets. To see it in full swing, check out the videos here.

So what do you think? How will the three tumblers fit into the storyline? Where does Catwoman come into play? How about the Batwing? Spin your theories in the comments section below!
