Exactly my point! But Ridley Scott would be right then in saying "it's a question nobody has asked" because even I have only recently started asking the question of "how did WY corporation know there was interesting stuff on that planet"? And thus that's where the sequel gets born from!
Ah, I see. I didn't quite follow you in your first post.
Yes, it seems WY is going to be in Prometheus. So it could answer that question.
