I think gold is going to be Aegon. My baseless theory of the day is that once Stannis fails, Tycho Nestoris and the Iron Bank of Braavos will back Aegon. Aegon then realizes that he really doesnt need Dany now to take the Iron Throne and doesnt want to share power and ends up betraying her when they first meet (or later).
I think the theory has a shot because, well, it would be pretty interesting, and it gives the whole Cersie defaulting on her loans and the Iron Bank backing other claimants to the throne more relevance/meaning.
