Only Five Possibilites for the 5th?

SyFy Portal reports that they've known the identity of the Final Cylon for some time and now they are willing to partially reveal what they know. They've winnowed the field down to, appropriately enough, five potential candidates for the Fifth of the so-called Final Five. Here's my take on SyFy Portal's Five and the odds for each:
If we take Ron Moore at his word that the Fifth and Final Cylon is not shown in the Last Supper image, then out of these five that means it must be Gaeta, Ellen, or Callie. It's certainly a relief that it won't be Zak Adama, Seelix, or someone who loaded ammunition on a Viper once. Sing us that song again, Gaeta, you know - the unstruck music.
