+ Sarah is clearly unhappy. His apparent unwillingness to put his name on the document and his recent comments make that clear. The problem he faces is at the next Conclave he, +Burke and others will lobby for their candidate, but may face a headwind because their counterparts from across the world will not be sympathetic to giving power back to Rome and the Curia. 

Francis was elected with a mandate to de-centralize and lessen the control by Rome. And, with more "Franciscans" getting Red Hats and fewer JP2ers and "Benedictines" being able to vote, +Sarah et al will carry the day.

By looking at the list of living Cardinals, it is not unreasonable to expect 20 to 25 more Franciscans getting Red Hats, with most replacing JP2ers and Benedictines.

The bottom line is - change comes slowly with the Church, but there is inertia that will keep it moving forward.
