Putting Star Wars in Battlefield is still closer to SWBF than Star Wars in CoD, or Crysis. And I personally trust DICE to make it good (maybe not great, but a nice experience).
I'm still not sure what Visceral will be creating (assuming that Bio->Star Effect and DICE->Star Wars: Battlefield), maybe they continue 1313?
I haven't played SWTOR so I can't say if it's good. I generally don't like MMO's.
