Just revealed at PAX East 2011: a new SWTOR trailer called Fate of the Galaxy. The trailer itself unfortunately doesn’t reveal to us any new details about the game, but is very well done, using only the in-game engine.
Tension between the Republic and the Empire is running high. The uneasy truce established by the Treaty of Coruscant is quickly tearing apart at the seams, and a return to all-out war has begun in all but official terms. A new generation of heroes, both light and dark, emerges to face the difficulties of these chaotic times, and fight for the fate of the galaxy in this most desperate age.
