Don't read too much into the new poster

I have seen plenty of discussion about the latest poster released showing different crew members and the Prometheus crashing into the Juggernuat. It's important to remember that Movie posters generally combine images from multiple scenes. So to assume that there are 3 crew members that survive the crash could be incorrect. It could be just 2 different scenes blended together. Below the ships crashing are 2 people running. Likely Shaw and Vickers as seen in the trailers being one scene. The 3 characters walking up the hill a different scene.
