First of all...BrotherDan, you were reading the 'Gods Kingdom of 1000 Years' book? Ho-LEEEE you must be bored. Or you got bored. QUICKLY.
Anyway, weighing in on the original topic--I don't think we're going to see much change in J-Dub numbers at or after 2014.
Think about it. How many J-Dubs of today would sit through a 'Book Study' of God's Kingdom of 1000 Years or The Nations Shall Know I'm the J-God--How? The same bunch who got dragged through the Revelation Climax book five times over? With revisions in beliefs that last go-round or two? How 'bout those enthusiastic hands-up commenters that led lively discussions through the Daniel book? Or both (agonizing) volumes of Isaiah? Oh for the love of Pick-Your-Deity, were conducting THOSE ever fun. *shudders*
You can't hold a topical conversation with two-thirds to three-fourths of the Witnesses today on the doctrinal holes because they don't comprehend the ins and outs and intricacies of their faith well enough to begin with. They DON'T. You'd have to teach their own beliefs to them before discussing why they don't add up.
Face it, folks. The 'Live Forever' book was apparently too complex a read for the new bunch. So tell 'em what to believe--and, of course, when it's their cue to applaud--and they'll suck it right down and ask for more. Except, of course, when the answer involves three or more scripture references in the paragraph. In which case they'll underline the sentences that match the words of the question, grunt a bit and move on.
