UPDATE - 17th. September 2010 (Designing the Lightside)

Taken from swtor.com:

Quote :: Guided by the Light Side of the Force, the Jedi are the ultimate defenders of peace, justice, and the Galactic Republic. The developers of Star Wars™: The Old Republic™ are taking great care to ensure that Players can experience the classical Jedi fantasy represented in the films by such iconic characters as Luke Skywalker, Obi-Wan Kenobi, Mace Windu, and Yoda.

At the same time, choice is at the heart of The Old Republic and Players can also explore many other ways they can take their Jedi characters. Whether that means walking the path of the Dark Side like Anakin Skywalker or simply adopting a unique combination of fighting styles, a variety of options will be available.

Watch Developer Dispatch: Designing the Light Side, and learn about the process involved in creating the Jedi classes for Star Wars: The Old Republic.
