It definitely has the feel of an alien remake. I can see it being a prequel though, the first people to find the space jockey which results in the company sending out the Nostromo. We'll find out.

On a totally semi-related topic, the announced that the Avengers premier will be in LA on April 11, almost a month before the movie actually comes out. There's not going to be too many plost twists left unknown if everyone is seeing it a month late. I can't imagine why the studio is doing that, other than maybe a timing thing with the stars.
