The article you posted about potentail papal successors is few years old and completely outdated. Cardinal Lucas moreira Neves died some time ago while cardinals Etchegaray, Martini, Schotte, Laghi and Gantin have all retired from their positions and are definitely no longer in the runing. Actually of those mentioned in the article I think only Arinze, Schoenborn and Tettamanzi (who in the meantime succeded Martini as Archbishop of Milan) could be considered viable candidates.
I don't follow this closely. My family is Catholic but I am actually a Quaker. It seems that it is very taboo to discus apparent successors amongst the clergy (especially the Cardinals), so I merely found the most recent article I could. Everything I have read over the last few years has indicated either an African or a return to the Italians. I personally think the next Pope may be French (the anti-pope?) but what do I know, that all comes from a couple of different prophecies I have read.
