Cool !
According to the official website , a new Congregation of the Oratory will be added to the Confederation on March 25. This one is in Prato, Italy, and will bring the number of Congregations in Italy to 19, and the number worldwide to 76.
They also have a little list of the other recently founded Congregations. Since the site is in Italian, I'll post the list here, in English:
Nancy, France - (1995)
Mexico City, Mexico- Our Lady of Peace - (1995) - (Mexico City is unusual in that it has 3 Congregations. Usually it's one to a city or town. )
São Paulo, Brazil - (1996)
Ilsede, Germany - (1997)
Maastricht, Holland - (1997)
Oudtshoorn, South Africa - (1997)
Metuchen, New Jersey, USA - (1998)
Poznan, Poland - (1999)
Philadelphia, Pennsylvania, USA - (2000)
Acicatena, Italy - (2002)

Pittsburgh's foundation date ? 1968. Young, but not that young.
