Dragons "know how to use the landscape, they can do bombing runs, they can land, they can walk around, they can perch on buildings, they can pick guys up".
There are different types of Dragons with different shouts.
Dragons appear early then "ramp up" as the game goes on.
Bethesda is not working on Dragonlings.
Fallout 3's lead designer http://static.zenimax.com/bethblog/oldcontent/emil.jpg voiced the Dragon Shout in the trailer.
Horses are looking good. They don't want to promise they'll be in though.
Snow can dynamically fall and clump onto objects such as "rocks, and chairs, and trees" in different orientations.
The team is not looking past Skyrim.
We'll see more shouts, dragons, and factions at E3.
