Courtesy of Fr. Zuhlsdorf, here are the relevant passages I wanted to see from the original I Media report:
"According to Vatican sources, the innovation rests in the fact that “Benedict XVI himself desired this approach” according to which “the traditional Missal of St. Pius V is not a separate Missal but rather a special form of the unique Roman Rite.” In the Vatican, as among the members of the new institute, it is stressed that “this accord corresponds to the requests once made by Monsignor Lefebvre”, separate from Rome in 1988.
"The new fraternity counts among its ranks, aside from five priests, some seminarians assured to be ordained in the near future. Dario Card. Castrillon Hoyos has said he will celebrate the first ordinations. Those responsible for the fraternity also count on the fact that the priests of the Fraternity of St. Pius X could opt to follow them and that they can found in different dioceses, “personal parishes”.
Fr. Zuhlsdorf gives the following analysis of it:
1) There is some bad blood between the SSPX and the FSSP as well as (probably) the Institute of Christ the King, which makes the FSSP and the ICK less than optimal alternatives for men of the SSPX who want to be in union with Rome. This new group offers a fresh possibility for those who were in line with the men in this new group who themselves were tossed from the SSPX for various internal reasons.
2) This seems to be main a French reality.
3) Benedict XVI is using Cardinal Ricard, a member of the P.C. "Ecclesia Dei" to put head pressure on the French bishops who, in the past, have been terribly hostile to anything having to do with the older form of Mass, etc.
4) Benedict XVI is acting, chipping away at the edges.
5) Card. Ricard suggests that this move is part of Pope Benedict XVI’s plans for "full communion".
6) The fact that this group is for former SSPXers suggests that it is not going to be accepting new candidates who were not in the SSPX. Thus, this is aimed squarely at the SSPX.
7) Given the fact of the plenary of the SSPX and the contact Bp. Fellay had with Pope Benedict XVI, it strikes me that His Holiness belives that there is enough discontent in the SSPX, or enough harmony with the positions of the former SSPX priests founding this new institute, that it was time to "strike while the iron is hot" so to speak.
