It seems to me, based on posters we've seen for the land anyways, that the Fab 5 will still have a decent sized prescence in the area, even though it's no longer ToonTown...I almost wonder if one of those tents back there will still house M&G's where you can meet circus versions of Mickey and the Gang.
No, the new meet-n-greet for Mickey and Minnie, at least, is now at Main Street in the Town Square Theater. Everyone keeps saying that this is their new "permanent" home. To me, "permanent" means "until the end of time". That, to me, means that this is the mice's new home at the park until the end of time. Or at least until the day something dramatic happens and they have to shut the resort down, whichever comes first.
