I can't wait for this, I've just finished watching season 2 and we'll have to wait until next year in the UK for season 3. I echo the suggestion that if they find Earth, it should be a future Earth, and maybe the humans on Earth don't turn out to be the saviours everyone expected them to be. Maybe they could be even worse than the Cylons, forcing the Galactica to face a choice - make peace with the Cylons and join them against Earth, or to join with their fellow humans on Earth. Definitely when they find Earth it is not going to be what we expect. I'd be really disappointed if it was.
On the otherhand, maybe the Cylons have already reached Earth. Afterall, they knew about the Tomb of Athena and Kobol's past.
And I have to say, being such a big fan of the original series, I didn't think I would like the new versions of the characters but they have really grown on me. I like both the new Apollo and Starbuck, and I don't think Apollo is pining for Starbuck at all. If anything, he's still in love with that woman he left on Caprica. And Edward James Olmos is brilliant, as is James Callis. I'd never have thought that Baltar could be the best character in the series.
