The idea of Leia as a villain is just too silly for me to take seriously. So I'll say no to that one.

I'm hoping the villain isn't a Sith. I posted my thoughts on this a long time ago, though I don't think it was in this thread. Assuming there's a Jedi Academy, I'd like the villain to be a rogue Jedi of sorts who teams up with some other bad dude and they do only vaguely bad things. Let's have some shades of gray (not fifty though).

I feel like Luke's era of Jedi is (or should be, from everything seen in ESB and ROTJ) a lot more "gray". I think that his triumph was showing stuffy old Ben and Yoda that they were wrong about what being a Jedi was all about and how the Force worked, and I'd be really surprised (and very grumpy) to see Luke being a stuffy monk like the PT Jedi.

Of course, Luke's teaching style might be a little too liberal, which perhaps leads one of his pupils to step just a little too far across the line...
