"Do you think the guys up there in New York have made a mistake [in their predictions about The End Times]"?
Years ago you would have never heard such a thing. More recently, I think it's being heard, though in a whisper. I do know of one longtime elderly JW who asked that on his/her deathbed. Faithful until death. Sad. A life wasted.
