The link below is 2 years old, but it is quite interesting given current events.
From the link:
The new appointments will boost the number of Italian cardinals to 25, giving them huge clout when it comes to electing a new pontiff on the death of Benedict XVI.
The "Italianisation" of the Catholic Church's hierarchy fuelled speculation that after Benedict, a German, and his Polish predecessor, John Paul II, the leadership of the world's one billion Catholics could swing back to Italy.
The last Italian Pope was John Paul I, who was elected in August, 1978, but died just 33 days later, his sudden death still the subject of conspiracy theories.
We shall see.
