While Scola and Schoenbern are both possibilities I think the chances aren't good of them making it. Schoenbern especially, I cannot see the Catholic church choosing a 2nd straight European non-Italian to be the next pontiff. Scola is a bit more likely on the other hand, he is Italian, and is in charge of an important Italian city, Venice. However, I still see the Italians pushing for Tettamanzi, virtually eliminating Scola.
MathProf - Rivera is 62 and has an outside shot at becoming the next Pope. He is the archdiocese at Mexico City and has done a good job of running things there and you're right is very conservative. Rivera has been a teacher at a Catholic school and an outspoken critic of Mexican politics. Miguel Obando y Bravo is over 70, but has virtually no shot at becoming the next Pope. Obando y Bravo was part of a church controversy in the 1970's when he accepted a Mercedes-Benz limousine as a gift from notorious Nicaraguan dictator Anastasio Somoza. Obando I believe also supported the anti-Sandanista contras in the mid 80's, another unpopular move inside the church. To be short MathProf, Rivera has a chance but Obando has none
