Update: Disney and LucasFilm showed off a wealth of new Star Wars footage at this year's San Diego Comic Con. Some of those clips have been released online. You can find all of them below.

Classic ships. Classic armor. Classic character. Disney and LucasFilm's new "extended" trailer for Star Wars: Rebels is loaded with classic trilogy goodness, including a brief appearance by Obi-Wan Kenobi, who manages to work a movie title into his message of, "Our future is uncertain, but in time, a new hope will emerge."

The trailer below gives us a good look at the conflict at hand, and what we can expect from the characters. From what I can tell, it looks like the narrative focus will be tighter than Clone Wars', focusing on a small group of characters united by their drive to build a rebellion.
