I went back to Gametrailers to the page that is advertising the Skyrim interview. They specifically say "no new trailer but Todd shares good info." I take that as no new footage. I think they're saving footage for E3.
It doesn't have to be footage per se, but they could be releasing more images. Trailers may be hard to make but screenshots only require proper camera position and a button press.
What I would like to see is simply a few screenshots or renders of the races. I wouldn't rule that out of possibility, though the evidence to indicate that happening is nearly nonexistent. What the evidence does indicate is that it will be more than a few screenshots of mountains released without any fanfare. Could be cities, could be characters, could be dungeons, who knows?
