I believe that the list of popes contains an error. My theory is that John Paul I was only pope for a month, so Malachy's list didn't include him.
Consider this; the designation of John Paul II as "De Medietate Lanae" (Of the Half Moon) would make a lot of sense, since he was pope during the rise of Islamic power and conflict between Christianity (US) and Islam (Iraq/Iran). The symbol of Islam is a crescent moon.
There is talk that the next pope could come from Africa or Latin America. FT.com article linked above says that some the papal candidates have connections to the Latin American church's utopian Marxist movement in the 70's and 80's. "De Medietate Lunae" -- (The Toil of the Sun) would be a fitting name for a pope from an equatorial region with ties to socialist/labor movements.
To Ryan Bailey the Mason, I'm so sorry I just can't even entertain the thought of listening to what you have to say about this subject. You of all people can't connect as to why we, as Catholics, look for undersanding in the writings of St. Malachy. Your thinking and comments are being used as a poleax in the midst of a Christian debate/discussion. Saddly, This is just a dirty little hobby for you....
