Sure it is. Where's the official announcement?
Motu proprio “after Christmas,” CNA reports

My Austrian friends just emailed me. Kath.net/Die Welt (Klaus Badde) report (my translation:) that the motu proprio liberating the Tridentine Mass for the entire Catholic Church has been given to about 30 bishops from all over the world in the Sala Bologna of the Apostolic Palace by Vatican Secretary of State Tarcisio Cardinal Bertone. The bishops had been invited to Rome for that purpose.
At the end of the meeting, in which the motu proprio was introduced together with a letter of explanation by Pope Benedict XVI., Pope Benedict met with the bishops. The document is about three pages long, the accompanying letter about four. From Germany, Cardinal Lehmann had been invited. The circumstances of the procedure make clear that the Pope was very interested to personally inform the bishops, in collegial manner, of the content rather than have them learn about it from the media.
The publication of both documents will take place on July 7th. It emphasizes the unity of the Roman Rite which will consist of an ordinary and an extraordinary form which are supposed to inspire each other. The ordinary/regular form will continue to be the new rite of 1969. The extraordinary form will be the Missal of Bl. John XXIII. of 1962.
I have stumbled into a friendship with a small community with undeniably and unbelievably close and wholly unfettered ties to B16.
Of course I asked about the indult during the end of May: these people have no doubt that there will be a universal indult that allows any priest to offer the 1962 latin Mass regardless of the wishes of the local bishop.
Does that make it official? No. But given the news reports today there now seems to be no reason to doubt that the indult is real.
