the latest Star Wars: The Old Republic timeline update.
Of course, if this second update doesn't just scream, "Smuggler class!" then we're not sure you were paying close enough attention. Then again, BioWare could just be trying to throw us off the trail by making the Smugglers such an obvious component to the back story. The problem is that, either way, you really cany have Star Wars without these guys somewhere in the story. Who knows, maybe they'll be called Scoundrels instead?
And of course there's the possibility that Mandalorians will be featured as an Empire class, or at least the new update seems to loosely imply as much. Either way, we should expect some kind of shady character classes to be announced sometime in the near future.
