Not surprising, given that they aren't using Gilead to train missionaries anymore. I think many of the countries in which the WTS has missionaries aren't adding to the bottom line and in fact may be losing money. So, why continue to build infrastructure in countries where you have no chance of turning a profit?
I don't see them making any radical doctrinal changes, simplying continuing in the long line of cost saving measures that they've been doing for the past several years. If you can't increase revenues, you need to reduce expenses. They have tons of money but are likely too heavy into big real estate and need to get more liquid which is why they're selling Brooklyn. It costs a lot to keep the buildings maintained and the lights on.
They aren't going out of business anytime soon but I believe they have moved past their peak and will likely slowly shrink over the next decades. However, I'm sure there will be a WTS or JWs around when I die.
