They will pump up numbers to keep breathing life into the "growth" claims as long as possible, but eventually the tricks won't hide the facts.
The apathy is already present and being covered up with rampant anti-depressant/anti-anxiety meds. (at least in the States)
That is probably why they are looking to cash $$$ in so much lately - to milk the cow before it's gone.
I wonder though if there will be a spinoff again like before?
The "reformed" JW's.
