Let me also add...
If BSG had or if Caprica does acknowledge multiple gods, even to the point of conflict, that would be something I would tune in for. I have contemplated giving Caprica another chance when it premiers next year. I had issues with BSG from the get-go when it was obvious every single character on that show was a PTSD sufferer. Caprica doesn't have that handicap.
After BSG ended, I almost suspected Moore was preaching. If I had discovered he was devout in some faith, I may have shouted such an accusation. As it turns out, he's a non-practicing catholic like I am (I'm a little further away, I suspect). Although I will say that BSG was not always innovative or brilliant (a conversation I won't begin here), I will say it took chances. Sometimes it worked, sometimes it didn't. I won't recant my opinion of the ending of BSG. I still stand by the view that the last hour was weak. I still think that if BSG hadn't authenticated a monotheistic god at the end, then Caprica would be stronger, as it would have balanced the playing field between the two faiths.
If they do end up balancing the field, then I would definitely return. The problem there is that the moment you add in one other god, the setting stops being monotheistic and the polytheists win; it instantly throws the team to the other side. Follow that logic.

Of course, they could also throw in the monkey that the god at the end of BSG was the last of the polytheistic deities or, stranger still, not a god at all, but an unusual third party (aliens, time travelers, etc)...yes, I understand that the latter point would be dumb.
My other conceit is that if BSG was a total fantasy, then the monotheistic god would not have to be related to ours. If BSG had ended without the "future Earth" coda, we could dismiss the setting (dismiss is not the right word but let's stick with it) as much a fantasy as Star Wars or LOTR and accept it.
I watched BSG and will probably watch Caprica because with the loss of shows like Farscape and Firefly, quality science fiction is falling by the wayside, forcing me to suck of the drops of Stargate and Terminator: TSCC. By next year, Caprica may be all we've got...that and Stargate Universe (oohh, pinch me). I probably will still watch it...because it’s a drug and I'm an addict...
