The latest sales estimates on Star Wars: The Old Republic (SWtOR) are at three hundred million units – that’s the population of the United States. Compare that number to the roughly 11 million active players of the most successful MMO game so far, World of Warcraft, to get an idea of what an Alderaan-shattering amount of success is expected here.

The Star Wars: The Old Republic blog has announced four new playable species for the highly anticipated MMO. These species are non-human (though humanoid in appearance), and apparently each of these species are restricted to one particular class. They are the Sith Pureblood, Miraluka, Mirialans, and Zabraks.

Last E3 (2008) we reported that the rumors for a new Star Wars MMO were finally confirmed. This E3 (2009), convention goers were treated to a lovely surprise consisting actual details on the upcoming MMO (release date yet to be announced) that’s being developed by BioWare titled Star Wars: The Old Republic.
