Looks like I've scooped Rorate on this one (he he, the only time I'm likely to!)
The Vatican Information Service reports as follows:
"As reported by news agencies, today, 16 May 2012, an Ordinary Session of the Congregation for the Doctrine of the Faith met to discuss the question of the Society of St. Pius X.
In particular, the text of the response of Bishop Bernard Fellay, received on 17 April, 2012, was examined and some observations, which will be considered in further discussions between the Holy See and the Society of St. Pius X, were formulated.
Regarding the positions taken by the other three bishops of the Society of St. Pius X, their situations will have to be dealt with separately and singularly".
