As soon as the announcing cardinal said the word "Josephum," I yelled out "It's Cardinal Ratzinger!"
Many in the crowd seemed to know at that moment too, as a roar went up and the cardinal had to pause a bit.
Mike Fieschko posted the Latin phrase the way the cardinal said it:
Annuntio vobis gaudium magnum; habemus Papam: Eminentissimum ac Reverendissimum Dominum, Dominum Josephum Sanctae Romanae Ecclesiae Cardinalem Ratzinger qui sibi nomen imposuit Benedictum XVI.
Dang!! I wish I'd seen it live!
