A kind WDTPRSer sent me a link to a story in the The Times about the Motu Proprio.
An article by Ruth Gledhill mentions the resistence coming from German bishops to the MP. She claims that the Pope will not be deterred. Here it is, edited and with my emphases.
The Pope is going ahead with plans to bring back the traditional Latin Mass in spite of objections from German bishops, sources have told The Times.
Pope Benedict XVI is understood to have signed an “indult”, or permission, that would allow Roman Catholics worldwide to celebrate the Tridentine Rite whenever they wished. At present the old rite can be said only with special permission from a diocesan bishop.
The return of the Tridentine Rite would represent a triumph for traditionalists and be an indication of the Pope’s determination to reinforce conservative Catholic doctrine as one of his most powerful weapons in the fight against secularism.
The document had been expected earlier but is understood to have been delayed after a seven-page document of objections by German bishops was sent to the Pope.
Among other things, the Germans were anxious about a Good Friday prayer calling for the conversion of the Jews. A wider revolt by bishops’ conferences around the world would have seen off the indult, but in the end the Germans were isolated in their protest. However, when the permission is published, it is thought likely to exclude prayer for the conversion of the Jews, which leaders of the German and the British councils of Christians and Jews have spoken out against.
It could also include an “opt-out clause”, allowing bishops to prohibit it at a local level, which would placate both the German and the modernist French bishops.
"Modernist French bishops"!!
In any event, I seriously doubt there will be an "opt-out" clause for any individual bishops. That would entirely negate the point of the document.
I also suspect the permission will be granted for use of the 1962 Missale Romanum as it is.
Part of the problem comes from the fact that many priests saying the "old Mass" are using some edition previous to the 1962 Missale.
