I kinda hope they're not the main characters anyway. Part of me wants to think Abrams - whether or not Kennedy even had this in mind when hiring him - is gonna introduce us to a whole new cast of characters just as he did in Star Trek. Yes, I know what you're thinking, "but, those characters in Star Trek already existed." Yeah, but the way JJ pulled it off made it feel like we were meeting them again for the first time.

Sure, it's a little more of a challenge to introduce characters no one's ever met before, but I would absolutely love it if halfway through the movie our protagonist is saved by a mysterious, cloaked figure who is then revealed to be Luke Skywalker. Yeah, I'm just theorizing, and all of this ultimately depends on Arndt's script, but it's fun to speculate....

This is a whole new trilogy. Why would you ever think they were making them the main characters again? Even George way back when was going to have 7-8-9 be about Luke's sister and presumably other new main characters.

There's no way that they're the main characters still. =P
