I reserve judgment on whether they will publish the partaker number, or the rest of the statistics in full online, as promised.
The GB always seem to take the easy way out. When faced with disconfirmation over the "generation", instead of having a fundamental reevaluation, they came up with the most ridiculous fudge.
Dropping the literal 144,000 teaching would be the brave but rational thing to do. But my guess is they'll go with an easier option. They may simply stop publishing the number and assert that the "real" anointed are declining in number without giving specifics. They've demonstrated they can tell JWs just about anything and they'll take it. JWs might not like it, but what are they going to do? Not much they can do. They have no power. They can shut up and accept it, or else speak out and be shunned. That's the rules of the game among JWs, as currently constituted.
