As you may or not be aware, some are starting to wonder whether this unannounced audience of all the curial departments with the Pope may have anything to do with the rumour of the Motu Proprio coming out anytime from this week to May 5th -- the date reported to have been said by Dr. Alice von Hildebrand as a possibility.
As I expressed in the comments earlier today, I've been holding off on commenting on these things (without any real sense of a Roman source), but after thinking about this particular meeting, it may well hold some promise that makes it worthy to mention.
