Are they going to discuss the different versions of the first vision that Joseph Smith wrote in this general conference? The conference is going to be over 8 hours long. SURELY there is time to discuss the different accounts? My guess at what they will actually do is that they will mention that the other versions exist, but they will gloss over the details. They won't present anything that would challenge the version they have been presenting for years and will make it sound like there is nothing significant about the differences between versions.
