I think nick's right..they will almost certainly stay as they are. There's really no reason for the FSSP or the ICK to be folded into the Society, and nothing says that all the traditional groups have to be folded under the same umbrella.
Diocesan entities such as ours will undoubtedly continue as they are.
However, I can foresee some bishops hostile to tradition using the argument that, well, since folks can go to the SSPX now, we don't NEED an indult in our diocese. Let's hope not tho.
