First off, you say that it we all use common sense and that it is just a trailer. When the Halo 2 trailer came out some people speculated and said it was just a trailer. Bungie included it with some added content, the bomb. The trailer stayed.
Now we come to Halo 3 trailer. In the Q and A with Bungie, they say there is a lot of drama in the trailer. Lots of theories, but not as deep as some make it to be. Bungie has been known to mislead us before.
My point is that this trailer for Halo 3 could be a vision. When Cortana comes into view and says something to the point of "I know you, your past and your future", maybe it is a sequence in the game where the Master Chief is being shown this vision in his mind. "This is how the world ends" as Cortana puts it. The covenant eliminating all of earth's defenses and activating the Ark to start their great journey (destroy the universe).
This could answer the one question bothering many people. The reason why the covenant do not shoot at Master Chief when they fly by him. In the first two games, a banshee can detect him from distances. If they fly right overhead, they will know he is there. Which leaves the choices to be, either they are allied with Master Chief, or he is just not there physically. This could be Gravemind showing this to him, trying to push the Master Chief to stop the covenant. That way the flood could thrive.
Sorry if this turned into a theory, carry on.
