Teaser Trailer - Anchorman 2 - The Legend Continues

The teaser trailer won't make any sense to someone who hasn't watched the previous movie. For who have seen the first movie, they can assume that the story of each character will stay similar.
The teaser trailer doesn't reveal anything about the story at all.
Additionally, the teaser trailer only shows the main four characters of the movie. The style of the characters continue from the first movie, they are the same. Doesn't contain much text except for the movie name and the release date (2013).
