I don't see the preaching work lasting another 10 years. To sum up the wt message in one word is: " generation" but now it seems to have switched to songs and cartoons and videos about a Christian way of life and Christian conduct -as if wt is gearing up for another century of preaching., while concurrently teaching that God Kingdom Rules. This translates into money because people are not comforted by watching movies about being a good Christian as they wait to die of old age and sickness with no end in sight; While wt message before was that the end would come in their lifetime. -Anyway, in the 5/15 SL broadcast, where SL informed the world community of JW that WT was in financial need and compared his request for money to that of the israelites who responded with an overflow of wealth, only received in the 1/16 SL broadcast, a response from a little girl sending a very sweet letter - and that's about it. The JW worldwide community did not respond by sending wt any money.
If what SL stated in his broadcast is truly the case, wt finances is grave but who knows if wt will manage or when they will actually run out of money. Whatever the case, I think that preaching is not going to last long.
