As for when they'll actually be released? Your guess is as good as anyone's, including mine. Unfortunately I don't have any kind of inside line on stuff like this (though it'd be nice if somebody would throw me a friggin' bone for tirelessly promoting this game for damn near a year now, y'know? :) ). I mean, you want to say, "It's gotta be before Christmas, right? I mean, come on- it's definitely a "Shut up and take my money" situation, isn't it? Closest thing to printing money FFG could possibly do?
Just remember how we all said that about Wave 2 about this time last year and that dropped in March. I don't mean to sound like a pessimist, and trust me- there's nothing I'd love to do more than be flyin' that Tantive IV around my dining room table while the snow blows around southern Indiana the evening of Christmas after the kiddos go to bed, but much like my feelings about the new Star Wars movies they're making, I'm kinda not getting my hopes up based on past experiences.
Sidenote- those friggin' space tile things still haven't been released? Good Lord, how long has it been since they announced those?
