Hahahaha! Oh, that's just funny. See the reason why they are delaying the trailer is because the movie isn't about Aliens Vs Predator, its about a Clown Vs Predator. It starts off with this new clown right. He is trying out his new flower gun thing, so he goes out in the back yard to give it a test. Anyways, little does he know that there is a stealthed Predator right in front of him, taking a whizz. The Predator doesn't detect him because he has spent the whole afternoon making fairy floss at the local ice cream store. So the Clown accidentally shoots the Predator, and the Predator gets pissed, and engages the Clown, thinking the flower gun thing as an actual weapon. Anyways long story short, the Clown kills the Predator by shoving his big red nose and wig down the Predator's mouth, and then grabs a pogo-stick and finishes him off. Then an Alien (which looks like a large dog covered in a garbage bag) kills the clown. Then the Alien kills itself. True story.
God............... What a disappointment.
