True - EXCEPT one needs to consider the issue of retirement.  Many of the JP2 and B16 bishops are aging out and are not going to be holding office very much longer.  That is already creating a shift in the balance of ecclesial power in the national conferences as well as the curia itself.  It's one reason that +Francis didn't clean the Prefects out at the start of his pontificate: he knew that a little time would do it for him.  The other advantage is that +B16 didn't appoint a large number of bishops - he wasn't in office long enough to do so.  And all we have to do is to look at the sort of men Pope Francis is appointing to various sees, and those he is naming as cardinals, to get the clear sense that, even in a few years, things are not and will not be the same as it has been.  We are in the midst of a true renewal.
