Well, the newest Batmobile does have an "ancestor" -- Frank Miller's version of the Batmobile in The Dark Knight Returns
graphic novel was essentially a tank, much as the movie version in Batman Begins
and The Dark Knight
As for how the Enterprise
will look in the new movie, I'm sure it will look very much like the original, only tweaked, like blue lighting on the nacelles, and the reddish globes at the front of the nacelles will probably look more like the nacelles of NCC-1701-E. In other words, I don't think fans will see a radical departure from the saucer/nacelles/engineering deck we've seen over the years. Not overly concerned about that!
