119 Cardinals that are under 80 are eligible to take part in the decision in about 2-3 weeks when the Papal conclave begins. There seems to be a consensus that we have zero chance of it being a US Pope.
The next Pope will be number 265.
The name of the successor to Pope John Paul II will be announced by a Chilean cardinal.
John Paul II has formally asked Jorge Arturo Medina Estevez, 78, to step onto the balcony of St Peter's Basilica after his death and the election of a new pope, and announce the name of his successor to the world's more than 1 billion Catholics.
His new brief comes with the title of protodeacon, bestowed on the person most awaited by the public after 119 cardinals meet behind closed doors in a so-called Conclave to elect the 265th pope.
