Okay, so potential spoilers!
And just a rumor, but Badass Digest reports that is has the skinny on The Force Awakens teaser trailer which is due in a few weeks. Is this what we can expect?
It's one minute long with the Force Theme played on woodwinds, softly, over flashing images of the main leads, each fading to black. There's no dialogue, just reveals of the characters. And then the music swells up into a full orchestral piece - perhaps what John Williams recorded, and we hear a female voice, likely Daisy Ridley's, saying "Wake up."
And then the title card appears - Star Wars: The Force Awakens - and we see the Millennium Falcon, firing blasters, coming right at the camera.
What do you think? Sounds plausible. A year out this is likely all we can expect!
