Sour Grapes, my one disagreement with your opening post: "My bet is that the Org will get very one whipped up on the new design that everyone will vote on selling the existing residential halls and building the newer cheaper versions."
The meeting made it very clear that congregations will no longer have a say in any of this. The LDC will make the decision as to where a need exists for a new Hall, which property to buy for it, which congregations will attend, what Halls need to be sold, or whether an existing Hall should be remodeled. The locals are completely out of the loop now.
