a few more popes like benedict though and a lot of these innovations may be swept under the rug.
either way there has always been some disparity between the east and west in practice, heck there still is in the eastern rite churches in rome.
as far as submission though i dont see submission ever happening. rome can come back to the table as the first amoung EQUALS sure, but will have to give up the idea that it can unilaterly act on the jurisdictions of other patriarchates.
Don't count on Rome giving up Her position on infallibility, cuz it's not the kind of thing that can be swept under the rug. At best, you can hope for Rome to take the position that future popes will no longer exercise it, though it could not be made binding on any future popes.
