Indoctrinated JWs don't have much substance to them anyway, many are robots. While it's true they may look forward to meeting others and the event, I still think many are listening and obeying the content of talks. That's why RCs, are so dangerous, because that's where many decide they are going to reach out to be pioneers or elders, and they give up their career and education goals.
They do listen, even if they are asleep. Aparantly it's a hypnotic state and the information is still going in, Steve Hassan explained it in his book.
