There is a preview of Obi-Wan up at
Actiontrip.com which includes a nice collection of screenshots from the game. here's the intro:
Although not officially dubbed as a sequel, Obi Wan is in fact, the continuation of the famous Dark Forces series from Lucas Arts. Over the past two and a quarter decades the Star Wars franchise has served as an inspiration to many generations of gamers, including myself. George Lucas' universe pushed the limits of our imagination further than we ever thought possible with an elaborate space adventure set in the future of shining knights and high-energy light sabres.
This is the first thing we've heard about the game in a while now.. maybe more will be uncovered soon
