If you want to know what the Pope might say while he’s in the US, Rocco says, you might take a look at what Secretary of State Cardinal Bertone has said in his appearances, particularly to the Knights of Columbus last summer.
This article by Fr. Gerald O’Collins, S.J. in America is quite nice – linking Easter, Peter, and Benedict:

In recent years ecumenical contacts between Catholics and other Christians have underscored the realization that authentic unity can be realized only in confessing the truth of faith. How best can we express that unity and truth? The essential truth of Christian faith could be formulated by saying, “The crucified Son of God is risen from the dead to give us his Holy Spirit.” The paschal mystery says it all. It is the basic truth to be maintained and passed on by all Christians. They have been baptized into Christ’s death and resurrection (Rom 6:3-4) to live together through the power of the Holy Spirit as the new Easter people of God.
What more could we expect from the bishop of Rome than that, like Peter, he strengthen the whole church’s faith in Christ’s resurrection? How could he better serve the unity of an Easter people than by proclaiming insistently the event that brought the church into being: the resurrection of the crucified Jesus? The pope must also lead the church with the loving authority of a chief pastor and be a model for all worshipers in celebrating the sacraments. But his great task for all the world is to announce that Christ is risen. Nothing can or should ever count against the power and joyfulness of that unique message.

One picture of St. Peter has fixed itself forever in my mind: a huge 17th-century painting of Peter’s martyrdom. The painting had been taken down from a church and brought for restoration to the studio of an Italian friend of mine. It shows two soldiers using ropes to pull Peter upside down onto a cross. The saint looks stiff and old, but his face is calm and peaceful. Two cheerful little angels watch the scene as Peter faces death and prepares to meet his master in glory.
Classical painters aimed to express the final character and significance of those they portrayed. They wanted to lead us to the reality and identity of the persons they had chosen to represent. That old painting of Peter in my friend’s studio in Rome catches the apostle’s courage in the face of death. Originally martyr (a Greek word) meant “witness.” Peter the great witness became Peter the martyr. He could face martyrdom with such serenity because he had faithfully witnessed to his master’s victory over death. He knew that Jesus had died but was now alive forever. In that resurrection Peter found his destiny and final identity.
When he was elected pope, Benedict XVI found his own final destiny and identity. A serene figure in white, he faithfully preaches the Easter faith that holds us all together. When I see him proclaiming the resurrection, he reminds me of another figure also dressed in a white robe: the angelic messenger sitting in the empty tomb of Jesus and announcing to Mary Magdalene and her companions: “He has been raised” (Mk 16:5-6).
In a few weeks Pope Benedict XVI will arrive in the United States. May he continue to fulfill fruitfully his vocation as Peter’s successor by announcing to the whole world the unique good news that is Christ’s resurrection from the dead. We could desire nothing greater for Benedict XVI than that he continue to show himself to be an Easter pope for an Easter people.
