This update from Rorate Caeli:
The Superior of the Society of Saint Pius X has signed the doctrinal preamble proposed by the Holy See, even if with some slight modifications

The response of the Society of Saint Pius X has arrived in the Vatican and it is positive: according to the informal information gathered by Vatican Insider, Bishop Bernard Fellay would have signed the doctrinal preamble that the Holy See had proposed last September as a condition to reach full communion and canonical regularization.
An official confirmation of the received response should take place in the next few hours. From what has been learned, the text of the preamble sent by Fellay proposed some non-substantial modifications regarding the version delivered by the Vatican authorities: as it may be recalled, the same Ecclesia Dei Commission had not willed to make the document (of [only] two, yet complex, pages) public, precisely because the possibility remained of introducing eventual small modifications which would not, nonetheless, distort its meaning.
The preamble contains, subtantially, the “professio fidei”, the profession of faith [Rorate note 1] required of those who are put in charge of an ecclesiastical position. And it thus establishes a “religious submission of will and intellect” be given to the teachings that the Pope and the College of Bishops “enunciate when they exercise their authentic Magisterium”, even if not proclaimed and defined in a dogmatic sense, as in the case of the greater part of the magisterial documents. The Holy See has mentioned repeatedly to her partners in the Society of Saint Pius X that signing the doctrinal preamble would not mean putting and end “to the legitimate discussion, study, and theological explanations of specific expressions or formulations present in the documents of the Second Vatican Council.”
The text of the preamble, with the modifications proposed by Fellay, and signed by him as Superior of the Society of Saint Pius X, will be presented to Benedict XVI, who, on the day following his 85th birthday and on the even of the seventh anniversary of his election, receives a positive response from the Lefebvrists. A response long expected and desired by him, who, in the next few weeks, will put an end to the wound opened in 1988 with the illegitimate episcopal ordinations celebrated by Archbishop Marcel Lefebvre.
It is not ruled out that Fellay’s response be examined by the Cardinals of the Congregation for the Doctrine of the Faith, in the next “Feria Quarta” [Wednesday] meeting, which should take place in the first half of May. Meanwhile, some further weeks will be needed so that a canonical arrangement can be established: the most probable proposal is that of establishing a “personal prelature”, a legal figure introduced in the Code of Canon Law in 1983 [Rorate note 2] and up to now used only by Opus Dei. The prelate depends directly of the Holy See. The Society of Saint Pius X will continue to celebrate Mass according to the ancient Missal, and to form its priests in its seminaries.

Rorate note 2: actually first mentioned in an official ecclesial text in the very relevant n. 10 of the Decree on the Ministry and Life of Priests of the Second Vatican Council, Presbyterorum Ordinis: “Present norms of incardination and excardination should be so revised that, while this ancient institution still remains intact, they will better correspond to today’s pastoral needs. Where a real apostolic spirit requires it, not only should a better distribution of priests be brought about but there should also be favored such particular pastoral works as are necessary in any region or nation anywhere on earth. To accomplish this purpose there should be set up international seminaries, special personal dioceses or prelatures (vicariates), and so forth, by means of which, according to their particular statutes and always saving the right of bishops, priests may be trained and incardinated for the good of the whole Church.”
