Did the founder of Opus Dei prophesy the Pope's Anglican Ordinariate? In a way, yes.
According to Msgr. Bill Stetson, Saint Josemaria Escriva, the founder of Opus Dei, visited England back in 1958. He frequented many Anglican Churches and was keen on rekindling fervor in England for the Gospel of our Lord Jesus Christ.
While visiting an Anglican Church, Saint Josemaria Escriva said in Spanish, "If we don't lend them a hand, the Christian Faith will die away in fifty years."
Well fifty years later (2008) the Anglican Communion became fractured through the ordination of active homosexuals and by the general erosion of Christian orthodoxy. Fifty-one years later (2009) the Holy Father "lends a hand" by establishing the Anglican personal ordinariate. Pretty amazing if you ask me. Saint Josemaria had it just about right.
