You have to admit though, if the Orthodox Church approved of women Priestesses (even if it was a Council), then thousands (if not millions) would leave the Church. That is, unless the Council was declared as null & void, and not ecumenical.
The people after all, rioted in the streets of the Byzantine Empire after the Council of Florence. All the Bishops there (save for one) agreed to reunion with Rome. But this reunion didn't happen since it certainly wasn't conciliar.
I would say that women ordination to the Priesthood in Orthodoxy will NEVER happen, because it will take the force of a Council as well as having to go through the people & the monastics to be approved.
