I missed it. What did they show?
You can catch the debut trailer http://www.gametrailers.com/video/vga-10-tba-game-2/708369.
Also: wild speculation commencing: I'm guessing there's probably no new game engine? Because it would take a bit longer to write up a new one. If we are still stuck with Gamebryo I hope there's some tweaks being done to eliminate things like the A-Bomb.
...also, evil dragons? Say what? :ahhh:
Meanwhile, wild hope commencing: Skyrim could be awesome. So long as we go with things like the http://www.uesp.net/wiki/Lore:Thu%27um and other esoteric strangeness. In other words, please let it not be "generic English medieval fantasy: now with 150% more snow."
