I heard that this weekend from a well placed source in the bishop’s Office.
It doesn’t seem to be a secret.
The Bishops already have a document from Rome outlining a new Lutheran Ordinariate.
It would be a Lutheran Use within the Roman Rite.
The media has part of the story already: As of October 2012: catholicculture.org/news/headlines/index.cfm?storyid=16080
