It's officially official, Bioware has announced Star Wars: The Old Republic. Set three hundred years after the KOTOR games, and thirty-five hundred years before the movies, the game will focus on the conflict between the Old Republic and the Sith Empire.
From the site:
Choose to be a Jedi, a Sith, or from a variety of other classic Star Wars roles, and make decisions which define your personal story and determine your path down the light or dark side of the Force. Along the way you will befriend courageous companions who will fight at your side or possibly betray you based on your actions. Together, you will battle enemies in dynamic Star Wars combat and team up with other players to overcome incredible challenges.
That's right, companions. It sounds like you will actually control multiple characters, at least when soloing, which isn't a mechanic that gets used often in MMOs. Their handy FAQ also talks about their focus in gameplay.
Star Wars: The Old Republic will be similar to other MMOs but with several key innovations. Traditionally MMOs are built on three pillars; Exploration, Combat, and Progression. We at BioWare and LucasArts believe there is a fourth pillar: Story. Our mission is to create the best story-driven games in the world. We believe that the compelling, interactive storylines in Star Wars: The Old Republic are a significant innovation to MMOs and will offer an entertainment experience unlike any other.
Also of note... you start as one faction but apparently can switch sides through various actions. I'm definitely excited to hear more details about this as they get released.
