I sure hope they don't end up on present day Earth like the first show. A cheap way to lower production costs and ruin the show.
I do have a Cylon question? It certainly appears that there is a supreme authority guiding them. Who (or what) decides that there will be models that all the others don't know about to protect the secret. Maybe they have been controlled all along by a human or combination like the Borg queen. What if that's the missing model?
