I'm OK with it as long as it's as good as J.J.'s Star Trek movies and is not complete crap like The Phantom Menace.
More than a prediction, I would love if Jar-Jar is the first character to show up in the movie and someone slashes him brutally with a lightsaber!
I think it's going to be a great movie, without the boring trade federation nonsense and hopefully all the comical relief will be actually comical and not stupid like Jar-Jar getting his tongue stuck around and an annoying kid exclaiming: "Yippieee!".
I hope it's not full of CGI. If it looks similar to the new Star Trek movies it'll be great to me. Yes, even with the lens flare. I don't mind it.
I hope the villain will be a bad ass and not an annoying whiny teenager.
I think it'll have great light saber battles which will not be like a ballet dance, but will look cool nonetheless.
It'll probably will have a lot of references to the original trilogy and hopefully almost none to the awful prequel trilogy.
Luke will probably be a similar character to Obi Wan. Old and wise, but he will remain somewhat youthful and good-hearted.
There will be a lot of teenagers and kids, but hopefully they're great like the kids in Game of Thrones and not idiotic like the kids from Twilight. They'll be good-looking, but most importantly good actors.
I expect it to have some ground-breaking innovative Special FXs, but as I mentioned before not looking completely fake with idiotic CGI.
I think it will be a bit more mature, but at the same time it'll be funny, especially when the original cast is included.
