The nice thing about having an evolving "truth" is you can change with the times. JWs have and will no doubt continue to. I've come across a number of JWs whos relationship with their religion is very similar to other main stream Christians i.e. not devout, letter of the law types, with more of a social approach to their faith. They may be viewed as flakey by hardliners from within but they seem content. These may become an ever increasing component, puting in very few hours (or 15mins) each month and missing meetings for other events. These people weren't dfed in my time and don't seem to be now.
When you leave being a JW you percieve it with fresh eyes and because you've been duped once start seeing signs where there aren't any. Cutting back on publication and centralising authority seems sensible to me, becoming a more lightweight and possibly responsive corporation. Locally they're experiencing a resurgence through immigration - but globally it seems like stagnation persists which means a gradual shrinkage may follow. Saying that, the winds of economic change may blow some into the kingdom hall.
