Also, I'm not sure I can believe any rumor that has Driver as a rebel pilot who undergoes a fall and becomes a full-on cybernetic Sith bad guy trudging in the snow all over the course of one film. Oh, and he's Han and Leia's son. And Daisy Ridley's brother.
There's not enough time in one film to introduce all of that convincingly in one film, not with all the other character and story angles we're dealing with (Ridley, Boyega, Luke, Han, etc.).
Yeah, a lot of people are trying to make connections between the new cast and old, but I can't see it panning out that way. I think it'd feel very forced.
I'm still convinced that Ridley's character is just some no-named scavenger, introduced to Boyega, and thrust into the larger plot as a consequence of her trade (checking out crash sites and abandoned locales, only to come across something of great value to entities much larger than herself). I also like the idea that our Sith character is Han/Leia's child (Driver) who has an unhealthy fascination with old Sith/Jedi artifacts, and ends up getting sucked into the dark side due to his own curiosity, thinking he's strong/clever enough to resist.
I guess if we end up seeing that there are a lot of force sensitive people out there now ("the force awakens"), it would make sense that Boyega and Ridley run around with lightsabers, but I don't care much for the idea of multiple Jedis in what will probably be our protagonist trio.
The way I'd like to see the main characters end up, a little based on some of the most prominent rumors:
Daisy Ridley - A scavenger, and our humble beginnings Jedi character. She's initially annoyed by Boyega (being hardened by the scavenger lifestyle, and probably not very involved in the overall Rebel/New Republic vs. Empire conflict) but sees him as a way off of Tattooine, so she follows him or takes him in and gradually warms up to him.
John Boyega - Military-trained, good in a fight, knows Imperial tech, which proves to be a great boon to the other heroes. Has to deal with the Empire looking for him, as well as winning the trust of everyone else. It's a bit hard to come up with anything for this character, since all we really know is that he is likely a protagonist from some point onwards, and he wears a stormtrooper outfit at some point.
Oscar Isaac - Hotshot pilot, older-brother Han Solo type character. He's very distrustful of Boyega at first because of his Imperial background, but he warms up to him after while. A serious guy when behind the controls of an X-Wing, but a bit more personable otherwise.
Adam Driver - Han and Leia's son. Probably a little pampered compared to the other leads. Force sensitive, but Luke hasn't been around for a long time, so he was never properly trained. He's possibly a bit irked that his uncle, the great Luke Skywalker, was never there to give him any training. This lack of guidance makes him very intrigued by old Jedi/Sith literature and artifact. Also means that he has poor control over both his emotions and abilities, and doesn't fully understand the dangers of the dark side.
