There have been speculative blogs by many people on this matter. An acquaintance in high school cut himself off from the world to join an SSPX monastery, so I really hope the group have forsaken their previous stance. The SSPX, or many of their members and sympathists believed that the Catholic Church had gone astray, inclusive within this was their general rejecting of the Vatican's stance that humanity and not the Jews were responsible for Jesus' Death. The current leader, has already stood out as seemingly opposed to those in his group who are antisemitic, hopefully he can lead them back from their less than ordinary ideas about the world.
The group has gained some empathy from Catholics who miss the aesthetics of the old Latin Mass, some of whom attend their services for love of the dead language, still the official language of the Church.
The papacy has yet to accept whatever statement the controversial group have made. Benedict XVI is hopefully smart enough to make the right choice, firstly for the mission of the church, and the people and image of the church and for the sake of the world. Secondly, that he makes the right decision, in relation to the group itself. One hopes the Vatican won't make a mistep, whether they accept or else reject the reply of the controversial group. When negotiations saw the excommunication of their leaders set aside, the Vatican had made a mistake, given one of the controversial SSPX group's Bishops /leaders had denied the holocaust had happened in World War II.
