I like the idea that it could be Ozma. We seem to be getting some solid Oz tie in towards the end of the season, including introductions to the Tin Man and the Lion. It's possible that the new characters are Oz related. Ozma and ????. any other male protagonists from the Oz series, I am not well versed on the stories beyond the first. the actual revelation of who the 2 characters are would not be done until the second half.

This also may offer a great way to boost Zelena's presence.

As for the Rumors, it would be really tragic, and very much anti-hope, if they were to actually kill Emma right after she gets married. So, I'd bet on her surviving the battle. Same with Colin, for the same reasons. That leaves Regina or Rumple, and solid money would indicate that if anyone goes, Rumple is the most likely candidate. And I could see him dying at the hand of Gideon, with Gideon becoming the next Dark One. (would probably happen towards the end, since the new Dark One would need time to appear at the vault and then get back)

But the wedding between Emma and Killian also raises the possibility that we either have BOTH Emma and Killian, or both will fade into the background. once they are wed, I can't see having one without the other, just like we have with Snow and David. I could see them retiring all 4 characters to live 'happily ever after' in Storybrooke, only reappearing as guest stars.

So, assuming the Rumple dies, and the Charming clan retire to the background, that would leave Zelena, Regina, Belle, Gideon, maybe Henry, the 2 new characters, and possibly Jasmine and Aladdin, to stick around for the reboot. And if the reboot is seriously Oz based, then Zelena's role will increase, and Regina will likely be a little less.
