That trailer was the wost thing they could do for this game, as it's created expectations that the actual game will fall far short of.
As discussed
here, the trailer was a pre-rendered CGI production that takes inspiration from the actual game's themes, tone and colour palate, but the actual game will have an illustrated, graphic novel look rather that the photo-realistic look of the trailer.
I predict that people who get psyched over this trailer will be sorely disappointed when actual gameplay comes out looking like
Star Wars: The Old Republic
