Tatopoulos Studios has posted some of the concept drawings of possible scenes from the movie
Alien vs Predator that were shown to 20th Century Fox, including one picture that is a potential spoiler.
For most readers the "spoiler" will actually be something that is a given. Whether or not it should be included in the movie is another matter entirely.

The movie will be directed by Paul W.S. Anderson (Resident Evil, Mortal Kombat) and stars a bunch of actors from bad movies and Lance Henriksen (Aliens, Alien 3) who has done some bad movies himself, but is at least something of an icon in the world of the Alien series.

Though the potential for this movie is high, the reality is that the popularity of the franchises alone is not going to make it good. It is not clear whether the producers, writers, and director realize that fact, but we will all find out later this year.
