Kaspar says he thinks the Pope will go:

A top Vatican official said he expects Pope Benedict to travel to Istanbul, Turkey, in late November for a meeting with Ecumenical Orthodox Patriarch Bartholomew of Constantinople.

Cardinal Walter Kasper, who coordinates ecumenical dialogue at the Vatican, said Patriarch Bartholomew had issued the invitation the day after the pope’s election last April.

"I referred this proposal to the pope, who welcomed it with great pleasure. I think Pope Benedict will make the visit to the Orthodox patriarchate on Nov. 30, the feast of St. Andrew," Cardinal Kasper told the Italian Catholic news agency SIR in early September.

Each year, the Vatican sends a delegation to Istanbul for the celebration of the feast of St. Andrew, patron of the ecumenical patriarchate, and the patriarchate sends a delegation to Rome for the June 29 celebration of the feast of Sts. Peter and Paul, Vatican patrons.
