Well, the next pope is supposed to be "Gloria Olivae" so I guess we'll see. That's commonly interpreted to indicate a Benedictine (Olivetan), but there's only one Benedictine cardinal and he's 93 years old - Cardinal Mayer of Germany. It's sometimes interpreted as a Jewish pope (since olive branches symbolize the Jews in the testaments) but the only cardinal that fits that description to my knowledge is Cardinal Lustiger of France (born Jewish).

Maybe olive-skinned? South American or Chinese?
