I don't think I am but it is possible. While I didn't watch the original much at all I don't recall them having human looking Cylons? Perhaps the first series is supposed to be the start of this all and the final five were created then?

I'm not sure really, but my theory is just that these five are from the last go through of this play, they talk constantly about how all this has happened before and will happen again, I choose to believe for their universe this is truth.

To clarify, I think that the final five predate the Cylon war at least; Tigh should have been heavily involved and I don't find it reasonable that they replaced him.

What do you think?

This is why I like this series so much, so many interesting questions.
