GOT fans: Who Will Kill Cercei Lannister? Predictions?

[Martina]

I really hope Dany doesn't die, btw. I want to see her and Jon Snow scooched together on the Iron Throne. Second choice is Tyrion although he has no real claim. Gendry does, but I'm not seeing it. Arya would make one scary ass Queen Consort though.

Re the original question, I am thinking Tyrion now, who also dies as a result of the fight with his sister.

I do think we're going to lose Tyrion. I don't think the fans could take losing both Dany AND Tyrion though, so I think she'll survive. And if she survives, she'll rule.
