Personally I'm really hoping Joss Whedon gets to direct the next movies. Avengers aside, he has a good rep when it comes to Star Wars style sci-fi -- Serenity and Titan AE come to mind. Plus he's said that if given the chance he would make a movie with lots of big space ships blowing up other big spaceships and frankly I'm sick to death of the Jedi.
Star Wars is the perfect universe for that. I mean hell, what if we got to see a Star Destroyer and a Mon Calamari cruiser duking it out? I mean like real ship to ship combat involving a Star Destroyer? Or imagine a space battle taking place in the ruins of the Death Star II over Endor? Arrgh, the possibilities!
On another note, given that Disney is great at preserving the classics, maybe, just maybe we'll finally get to have the original theatrical releases on dvd/blu-ray. I seriously want that, Star Wars in its original un-blemished form.
