I really hope this won't be a prequel. Because then, they're going to try to explain the Pilot. And I can't think of any way that any director (even Scott) or writer could possibly pull that off without it being utter balls. Then again, assuming they do go ahead with this and attempt to explain the Pilot and his(her?) origins, they had better bloody well not refer to it as a "space jockey"or I'm actually going scream and rage.
