You realize what this means: Star Wars Episode 7 won't have an opening crawl since Abrams will fear it gives away too much about the film. Yep, the same draconian anti-spoiler tactics currently plaguing Trek will be applied to SW. In fact, you can give up finding out anything about Episode 7.
We'll learn the actors who'll be in the movie, but we won't be told the characters they'll be playing.
Oh, and we can stop calling Episode 7. It's now Episode 07.
