For what it is worth, Marco Tosati, in La Stampa, offers today this about the internal battle in the Roman Curia over the draft. Here is my translation and emphasis:
When some time ago Benedict XVI sent the draft of the "Motu Proprio" to the Congregation for Divine Worship, the "anti-liberalzing" party, with the tacit endorsement of the Prefect, Cardinal Arinze, rushed to work on attaching restrictive modifications (for example, the need to raise the number of those making the request from 30 to 100), and sought in the doing to bypass the Secretary [of the Congregation, Archbishop Malcolm] Ranjith; who, however, managed to attach to the document, which was supposed to go back to the Pope, a long series of notes and marginal comments in order to bring the text back to its original meaning. …
You will remember that His Excellency Archbishop Ranjith has the reputation, even among members of the SSPX, as a defender of the older form of Mass. I have written of Archbishop Ranjith here and here and here.
Knowing His Eminence Card. Arinze, and having heard many positive things about Archbp. Ranjith, and having heard him speak in a reasoned and measured way about this matter, I have a hard time believing that this is fight between Arinze and Ranjith. Between others in the CDWDS and Ranjith? WITHOUT QUESTION.
Furthermore, Tosati mentions in his article a possible (optimistic) date of 8 December, Feast of the Immaculate Conception. In any event, nearly all the coverage mentions that it could come before the end of the year.
