+Vigano's excommuniation, of course, would mean nothing to me, for the same reasons that Pope St. Celestine declared the excommunications of Nestorius to have been null and void (even before Nestorius was formally removed from office) but even in terms of my perception of +Vigano. I doubt it'll happen because the Vatican simply don't want to go out of their way to draw even more attention to +Vigano. It's the same reason that they quietly allowed Bishop de Castro Mayer to continue Tradition in his diocese, and did not remove him ... because they figured that he'll eventually just die and disappear from the scene, and they didn't want to raise a bit stink about it. Outside of Traditional circles, no one had ever heard of him. So whether they do or don't excommunicate him, it would be for tactical reasons and not out of principle. While it might be interesting to read +Vigano's reaction to such a thing, what the Vatican decides to do or not do has no bearing on my perception of him.
