At the end of the Rogue One: A Star Wars Story panel this morning, there was a small trailer shown. The trailer was just about a minute in length. We will not be posting any videos from the trailer as they asked everyone put their cameras away and not film it. Here is a description of what the people at the panel saw:

Tatooine music from A New Hope opens over LFL logo
The presumed young Jyn Erso runs on a green planet (probably the fourth planet we haven’t had named yet)
Young girl runs towards camera, an Imperial-type shuttle flies by her.
Then we see adult Jyn running from evil people
“Everyday we grow weaker” -Jyn
Shot of captured Rebel pilots being escorted by Stormtroopers we saw in the last trailer
It appears Cassian watches them pass them by
“While they grow stronger” – Jyn
Death Troopers march on the green world, showing the same shot we saw last trailer but slightly longer here
“This is our chance” – Jyn
Shot of Mon Mothma at war console we saw last trailer followed by Cassian crossing his arms like in the last trailer
The rebels running through the jungle, Vietnam-style. Lots of tall trees.
“To make a real difference” -Jyn
Stormtroopers walking in the water like the EW piece.
Two Imperial officers at a console looking very uncomfortable
Krennic with his head down standing in front of Death Star materials like the last trailer.
Desert type of planet–Jedha–a ship lands with four wings that unfold. There are buildings to the left while a Star Destroyer looms above
Pao opens his mouth to the camera during action
The four-winged ship explodes near the ground
Rebels (similar to the Endor soldier) duck from the blast
Krennic walking in the puddle with his white cape
Jyn and Cassian in disguise running down a dark hallway
Cloaked figure kneeling before the illuminated tube/tank (old shot)
Stormtroopers running down hallway of the train station set (old shot)
Baze running towards camera with gun from last trailer
Over-the-shoulder shot of Jyn turning around with Stormtroopers in front of her
Cassian running towards ramp under fire
Shot of Death Troopers

Chirrut using his stick on a dumb Stormtrooper
Star Destroyer in front of the Death Star
Death Star laser dish being put into Death Star orb, seen in last trailer
Death Star red stuff with Darth Vader breathing
Rogue One
December

And that’s what we didn’t see if we watched the live stream today. While it would be cool to see it, it really amounted to about a TV spot’s worth of information and new stuff.
