EDIT: The NDA has been lifted, so feel free to ask questions and I'll answer anything I know.
So, anyone going to be playing this? I definitely am. It looks to be amazing, and BioWare makes nothing but great titles. They're the guys that made the Baldur's Gate series back in the day, Knights of the Old Republic 1 & 2, Neverwinter Nights 1 & 2, Dragon Age 1 & 2, Mass Effect 1 & 2, (and the upcoming 3) etc.
For those that don't know about it, it's a major MMORPG (same type of game as World of Warcraft) being made that takes place in the Star Wars universe. It takes place about 3,500 years before the Star Wars movies.
They've got a bunch of videos here: http://www.swtor.com/media/trailers - I particularly like the Taral V developer walkthrough, as it showcases flashpoints, or instances as they were referred to in WoW.
...Also, there's a GUNSLINGER advanced class!
