Trailer was pretty neat, but it doesn't change the unease I have about the new trilogy. I was a big reader of the storyline that went past the original trilogy, and they basically said they've retconned all of it just for these movies.
I'm a huge Star Wars fan and can't wait to see how they are going to connect the dots between the old and the new. This could be make or break for Disney if they do it tastefully. Interesting release date though ... December 2015? I wonder what they're thinking ....
With what J.J. did with the new Star Treks, I'm confident Disney's empire is secure. Not to mention them acquiring the marvel rights, some serious franchises right there.
