Jesuit Scholar, I think you have identified the extermination of the last hope for JW schoarship. On the other hand, there never was much hope; it must be impossible to move from pyramids predicting the End to serious theology. Right?
On the other hand, the Mormons show some signs of attempting to be taken more seriously. I've read serious defenses of some parts of their approach and heard of some LDS writers attempting to engage with non-LDS writers. Both of these small steps are impossible for JWs, it seems to me.
On the other hand, the LDS have one of them university things, which is well-regarded.
