I saw the trailer for The Matrix Reloaded and The Matrix Revolutions yesterday as well (there is one trailer for both films, viewable here). I hope this was just a teaser trailer, because it did little to really whet the appetite for these two films. As far as I could tell, it consisted solely of Morpheus saying something mystical-sounding followed by a series of effects shots that look like extensions of the fight scenes from the original film. There was no hint of story at all, except to refer to a "war". These films aren't due for another year, so presumably this isn't the last of the trailers for them.
