It is simply incoherent to maintain that the anointed were selected first, at the same time as endorsing the view Jehovah was still selecting anointed ones when there were already millions of Jehovah's Witnesses available to choose from. I am sure Witnesses will spot that flaw pretty quick.
May Jehovah hear you, slim...
It is at least as incoherent (and, to me, even more obvious already) that (almost) all those who were prospective members of the "great crowd" when it started to be "gathered for survival" will not be part of it because they are already dead 72 years later. Who among current JWs ever thinks of that?
I don't see the WT dropping the "earthly hope" anytime soon because it has been successfully integrated by most JWs and it significantly contributes to their originality on the religious market. But that can easily be maintained even with a figurative interpretation of the 144,000.
Otoh, it takes only one straw to break the camel's back, and it is hard to predict which one will.
