Speculation continues to run rampant on who the final Cylon is and how that person (well, that machine) will change the course of human history.

While you won't find the identity of the final Cylon as a spoiler on Airlock Alpha, we can share one tidbit: Viewers may fight out who is the last Cylon sooner rather than later on "Battlestar Galactica."

"If a few people had their way, the Cylon's identity would've been revealed already," a source told Airlock Alpha. "They are pivotal in the final batch of episodes, and we're not going to wait until the end to show you who it is."

According to multiple sources, the final Cylon was originally going to be revealed at the mid-season break, which just aired a few weeks ago on the SciFi Channel. It's not clear how the final Cylon would've been incorporated into the episode, but word is that it would've followed the twist at the end of the episode ... something that would've made the episode far heavier than it already was.

There is a bunch of speculation on who the final Cylon is ranging through all the main characters not already revealed as Cylons, and even some of the animals.

The secret, however, has been kept very safe, although the Cylon's identity is starting to float around some circles after an apparent leak from filming. However, this seems like a secret that many fans -- and even news outlets like Airlock Alpha -- are more than willing to keep, as it could soften some of the excitement leading into the final episodes.

But don't be too focused on this final Cylon, our source says.

"Everyone is talking about who it might be, and that's great. But there are far bigger fish to fry in this universe, and who that final Cylon is just one piece of many in this very intricate puzzle that we've put together for the fans. It'll be a finish worth waiting for."

Of course, none of this has been confirmed by SciFi Channel, so it should be treated as any rumor would.

"Battlestar Galactica" is expected to return to the network in early 2009.
