This morning The LEGO Group posted on Facebook a render of LEGO figures standing in the same poses and set as the Rogue One cast photo released last fall.
There’s a great amount of speculation if these are the same minifigures we’ll see when the Rogue One: A Star Wars Story sets are released this fall. The short answer, to me, is “not quite” – a few people pointed to missing features, but I see limbs bent in ways that they shouldn’t/can’t in standard minifigures. So I think they’re probably similar to some we might see, but this scene is rendered.
Both images are shown below for you to compare how accurate the LEGO version is.
