Two unknown crew members

Hi everybody, this is my first post. I was asking myself: who are the two unkown guys at 0:59 of the Prometheus Full Length Trailer? My opinion is that they are Yutani Corporation employees. They are very different from the others, and the colors of the label on their dress remind me the Yutani logo http://yutanicorp.com/ If this is true, maybe it means that they are observers sent by Yutani in the biggest Weyland mission ever, leading to the fusion of the two companies. A big part of the story could be related to a conflict among the two companies. What do you think about this?
