Yes, the ironies keep piling up. Pope Benedict will have a strong ally in these Anglicans who will be joining the RC Church as a corporate body. The numbers will not be huge, but the influence of these Anglo-Catholic converts will far out weigh their numbers.
I don't mean to sound argumentative, but I don't see this happening. They just want to be Anglicans in communion with Rome. That's really all they want. I don't forsee a great deal of interaction between these Anglican enclaves and Catholic ecclesiastical structures. I don't forsee the vast majority of catholics even being aware of the development, once it happens. Nor for that matter, will most "remaining" Anglicans make much of a deal over it.
I think people are really getting carried away with this. The ordinariates will continue to operate in pretty much the way they always have - inlcuding electing their ordinaries (episcopal elections will be subject to papal approval). The difference will be transparent to most people outside the ordinariates, but will be deeply felt and deeply appreciated within them.
At some point, perhaps fairly early on, some kind of superstructure might be put together so that Rome isn't dealing with dozens of separate ordinariates who don't deal with each other, but that certainly remains to be seen.
More reforms are coming. There is a list of changes to the Mass on the USCCB website.
I am so ready for them.
