I've watched the videos of all the classes. The bounty hunter and rogue (uh, i don't remember the name, but it's the "Han Solo" class) both look fun, and they've made them interesting, but there's still no way on earth my first toon will be anything but a Jedi or Sith.

So ya, it will be a problem. I'm pretty sure the first few months will have an over abundance of jedi/sith and then it will start to even out, at least a little bit.
