Yet those decisions have not entirely materialized...perhaos in 6 monthes more will be known if they do.
Jwinch, your speculation has basis in truth but it seems to me to be an unlikely theory.
#1 Because there are not many western rite churches around.
#2 Because there are a number of instances a degree of cultural and liturgical incompatibility. IE little use of latin, ex-protestant ministers/ex-protestant congregations who have a "low mass mentality" (liturgical minimalism). For example many do NOT like to pray the rosary.
#3 Odd as it may be, many Roman Catholics attached to the latin mass are in particular ways theologically the arch-nemesis of the Orthodox. Liturgically they are their friend, but not necessarily otherwise. Many have the most anti-pathy toward the Eastern Orthodox of anyone I have ever met, even if they do respect the byzantine liturgies. This is because they have often an attachment to the the older latin teachings and customs that have divided Roman Catholics from the Orthodox for centuries and refuse to let go of them. So one could also say that many of them are the least likely to ever convert.
My experience is that the average roman catholic who attends the average parish with the 1973 liturgy is more likely to be open to become Eastern Orthodox because they are less knowledgeable about their faith, therefore they have less to lose, as they never knew as much in the first place. The little customs they cant keep as Orthodox that the others refuse to let go of, they may not mind. While it does happen that those labeled "traditional" Roman Catholics do become Orthodox at times, they are more of an unique exception than something normal. Often times they are the people who love patristics more than they love st. thomas aquinas scholasticism. If you love the developments of the first millenium latin church more than the second and have a conservative liturgical ethos, you're going to have a sympathy for the Orthodox whatever kind of catholic you are.
Yes, Jwinch, under the right circumstances what you're saying could happen, as each western rite church is unique. However, its more likely they'll end up in the byzantine rite. Otherwise, the most likely possibility is that they will end up in some form of Roman Catholic church instead...schismatic or not.
