Personally I'm hoping the new movies don't make the Jedis (or the creation of a new Jedis Order) the main focus of the story. We already saw more than enough of them and their Jedi code in the prequels, which turned out to be not such a great thing after all.
Not to mention the heavy focus they've gotten in TCW...
I'd rather just go back to the ragtag group of characters again, with just one of them that happens to be a Jedi.
And surely it's possible to come up with a worthy villain in SW who's not an emporor or Sith Lord...
The conflict between the good and evil as embodied in the war between the Sith and Jedi is at the center of the Star Wars Saga. You can't have SW without a Sith Lord.
