Cardinal Antonetti was created Cardinal in the Consistory of 21 February 1998, and his passing made changes to the composition of the College of Cardinals. The College of Cardinals now consists of 205 members, out of which 113 are Cardinal-electors and 92 are Cardinal non-electors (reduced by 1 due to Cardinal Antonetti’s passing).

Barring any future deaths, the next event involving the College of Cardinals would be the aging out of Cardinal Godfried Danneels of Belgium from the electorate on 4 June 2013, when he turns 80.
