The "low church" crowd also have the REC and AMiA -- the former is the largest "breakaway" crowd, though as they did that in the late 1800s one could call them well established. The AMiA, under the African archbishops, is very busy planting new churches, and the Global South is providing oversight for individual breakway parishes.
But I will note that most of the Continuing churches are more catholic and NOT under the Global South -- particularly the APCK, I will note! There seems to be a shift towards Rome now, with the TAC certainly leading the way.
But I will also note that there are Anglicans going Orthodox as well, as noted recently here, for example.
I think if folks are going to survive as a unit that is even faintly still "Anglican", larger groups are going to have to coalesce together to reach critical mass.
Around here, the individual parishes are sort of wandering in the wilderness wondering what to do. It's tough.
