Star Wars: Rogue One Trailer - 10 Things We Want To See

Rogue One has a stellar cast, and the likelihood is that most of them will be making up the band of Rebel spies who steal the plans to the Death Star. 

I'll go into more detail later on Felicity Jones and Mads Mikkelsen, given their more prominent roles, but the rest of the talent to introduce includes Forest Whittaker, Diego Luna, Donnie Yen, Riz Ahmed, and Ben Mendelsohn. Most of those will be Rebels, and some sort of quick team introduction, briefly focusing on each member in turn, would be a great way to establish them without giving too much away at this early stage. 

Alan Tudyk's role is particularly interesting, as he is playing a motion-capture character - that means we're probably less likely to see him in the trailer, as the effects won't be finished, but a tease of what exactly he is would be interesting.
