I never said the changes would be "progressive" I just think it would be a good opportunity to make changes. Historically, the WTBS, has made changes to all sorts of things (doctrine, prophecy, administration, etc) about as often as most of us change our socks. Getting rid of a lot of weak members would make the changes easier.
I still don't think these new designs are going to be money-makers. Either the WTBS is not planning on trying to resell these ugly-ass buildings for lots of money; or they have the worst real estate advisors in the world.
