What did he mean? Fr. Luigi Villa said that Pope Pius XII spoke of himself as "the last pope".
What Pope Pius XII meant, I can only guess, but from what an SSPX professor at the Virginia seminary told me, it is generally known that Fr. Luigi Villa died as a Sedevacantist.

Pius XII himself said he was the "last Pope"
Jean Guitton was a noted French Catholic philosopher and theologian (1901-1999). According to a book by Fr. Luigi Villa, Guitton wrote in L'Osservatore Romano, October 19, 1960, that Pius XII himself had said that he was the "last pope." Following are excerpts from Fr. Villa's work, Anche John XXIII beato? (John XXIII "Beatified" too?), published in June 2000:
Wrote Jean Guitton (Pantheist and Bergsonian), friend of Giovanni Battista Montini, "Pius XII knew it, he himself said he was the 'last Pope,' the last link of a long chain. And yet in those years of the 1950's, the Church was thriving. But Pius XII knew an unprecedented crisis was in the making, 'in the very bosom of the Church,' as Pius X had already said. And that came about, in fact, with the election of John XXIII. Modernism exploded violently, in spite of Humanae Generis, issued by Pius XII in 1950. Jacques Maritain shared this view: "The modernism of the time of Pius X, compared with the modern neo-modernistic fever, was but a mere hay-fever." In fact, with Pope John XXIII the situation was reversed. The Progressives popped out from everywhere.
. . . John XXIII presently thought of appointing new Cardinals. Obviously, the first, whom he personally dictated, was Monsignor Montini, although he knew that Pius XII had kicked him out of the Vatican, and wanted him excluded from the Conclave, and for that reason he had refused him the purple habit. And we are still suffering from the consequences of John XXIII's action.
That too is a clear indication that John XXIII, far from having been a Pope of transition, was a real reformer and transformer, such as the Church had never known since the days of the Counter-Reformation. A new revised Church, today called "Conciliar," (quod dixit Cardinal Benelli).
