I've been talking to people in real life and online about a site that as far as I can tell looks as if it's an official George Lucas Star Wars site. There's lots of interesting stuff there. It has plot synopses of episodes VII, VIII, and IX. They don't sound all that thrilling, but these are pretty general at this point, and many things would all depend on the director. Lucas says he's got a short list of directors that would pass muster for doing these.
There's a list of Midichlorian counts for most of the major characters, but you can see from the most powerful Jedi list that a Midichlorian count doesn't always line up with how powerful a Jedi is.. There's a history of the Jedi and the Sith, and Lucas (supposedly) answers questions in a blog format.
