Watch the teaser trailer of Batman Begins, coming in a year's time, and an unofficial video clip (6.5Mb Quicktime) of the new Batmobile (or Bat-Tank, by the looks of it), in action.
I'd save it into your hard drive if I were you. It does not look like WB will let this kind of thing float around, and the site hosting it may also find the load too heavy eventually.
