Well ,that is a strong possibility. But remember Vaders key mission in ANH is to find those transmissions that were intercepted during the battle and its clear they make it only to the one ship which the Empire then captures. He then spends a fair amount of time torturing Leia to find out where the Rebel base is and failing, until Han flies her there in the Falcon from the DS. So it seems there is nobody left alive from the Rogue One mission to capture and interrogate other than who is left on the Blockade Runner otherwise the Empire probably would have done so already, particularly Krennic as that is his speciality.
BUT:
We see Jyn at Yarvin early on in the trailer and although we have seen her running and carrying what looks like a data pod towards the Walkers in what might be the final battle I don't see that being handed over to the Rebels physically, as we know the data is beamed off the planet to the waiting Blockade Runner that flies in to intercept it
There is that tall antenna with a radar dish on top of it behind the Walkers in the trailers, so I wonder if thats what they decided to try and reach in a last ditch effort to transmit the data. In the EW cover photo there is also what looks like the Empire base on an island (which makes sense as the tall Walkers would be able to wade between them in the shallow tropical seas).Also we see Krennic wading towards the same place around a lot of blazing wreckage which again suggests a huge final battle on the tropical sea planet.
So do we have a last stand here in which everyone is killed or , if Jyn has been conscripted forceably by the Rebels much against her will, does she make an escape after completing her part of the deal in the chaos of battle when Vader goes chasing after the BR, and disappears back to her "Underworld" life as a smuggler?
