I face some disappointment if it's none of these. I think it has to be big, and dramatic, and the other candidates outside this group are harder to make dramatic.

I've suggested some elsewhere in the blog, such as Joseph Adama. He would be a nice shocker even though never seen yet onscreen. Cain was an interesting candidate but Razor made her seem less interesting in this role to me. Gaeta has been a popular choice, and he does have some mysteries to unravel over stabbing Baltar and a few other tricks, but I find him anticlimactic, as is just about any other of the lesser characters.

So my guess at this point is that Moore would not go so far as to reveal at this point that the final Cylon is not one of those in the picture. It's one of those questions he would be comfortable giving a deliberate misdirection on if asked, like "Is Starbuck deead?"

If it has to be somebody not in the picture I like Joseph Adama the most.
