As far as the crawl, I would be really surprised if it's not included. It will will probably just have each film's subtitle as the header followed by the narrative, similar to is in most SW videogames.
To be honest, I'd be perfectly fine if they left out the crawl altogether in the new movies. They might have seemed kind of novel and cool originally, but by now it just seems tired.
I'd rather Abrams and the other directors just jump directly into the story.
