I hadn't even heard of this until very recently, apparently its an upcoming Star Wars MMORPG from Bioware, who's previous games include SW:KotOR, Neverwinter Nights, Baldurs Gate, Dragon Age: Origins, Mass Effect... the list goes on ^^

So i went over to GameTrailers and checked if there were any previews and whatnot, and i found this trailer from E3 2009:

Jedi VS Sith Cinematic Trailer

How crazy awesome was that?
