Galactica will find Earth in season 4. So says Adama himself:
iF MAGAZINE: What’s coming up for season four?
EDWARD JAMES OLMOS: It’s fantastic. I think they’re going to discover some very important issues about what the fan base really, really wants to see and what’s to understand about this show. We’re heading into the final season. This is the final season as we speak. All of us are very saddened by that, but we always knew there was going to be a conclusion and we would find Earth, so we will be finding Earth this season.
woah. awesome. I am not saddened by this; far better to go out with a strong finish than drag it out forever. I’ll buy the DVDs as penance for having torrented the series all along, and then move on to the next thing, probably Heroes or Firefly (or both).
UPDATE: Olmos repeats the news in a separate interview:
When asked about the next season of Battlestar, Olmos had this to say, “This will probably be the most extraordinary season of Battlestar, it’s the final season so, it’s definitely going to be the most vicious.”
IESB: Final?
Olmos: You heard it first.
IESB: Are you serious?
Olmos: Very much so.
vicious? I kind of like the sound of that.
