BioWare announced today the project many people assumed they were working on: a Star Wars MMO (that isn't Galaxies). Essentially, it's going to take the setting, style, and basic principles from BioWare's popular Knights of the Old Republic duo of games and make it massively multiplayer. At a press conference in San Francisco earlier today, a BioWare representative labeled TOR (should we start calling it that?) as "Knights of the Old Republic 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12-plus." So far all they have is some concept art and a couple screens.
