Todd Howard has said time and again that at the beginning of the game you are a prisoner going to your execution.
There is nothing else to the footage....except that it showed off some of the awesomeness Bethesda should be proud of
The main quest is still a mystery.
How you know you are dragonborn is a mystery
Where you meet Esbern is a mystery
Basically we really do not know much more than Todd Howard has made known to the world already
So why the harsh clampdown??
