The General Women's Session happened on Saturday. I'll give that its own post. Linda K. Burton, Relief Society General President, did not speak at it, so I would expect her to be one of the speakers this weekend.
The Any Opposed group plans to get into Conference again and voice dissent. I believe their goal is to never have a unanimous vote in Conference again. I really hope this doesn't result in what happened in 1980, where they just stopped reading the names of the leaders of the church for a sustaining vote for a couple years.
In addition to the twelve talks that the Quorum of the Twelve will give, the six talks that the First Presidency will give, and the two talks that female auxiliary leaders will give, they usually have two members from the Presidency of the Seventy and one member of the Presiding Bishopric speak. Last session saw L. Whitney Clayton, Ulisses Soares and Gerald Causee fill those slots. I expect at least one of the new Apostles will be from the Presidency of the Seventy, and therefore my guess would be that whoever the new member of the Presidency of the Seventy is, he'll be one of the speakers. As Dean Davies spoke in the Conference before, I expect Presiding Bishop Gary E. Stevenson to be one of the speakers whether he's a new Apostle or not.
In the Second Quorum of the Seventy, Koichi Aoyagi of Japan is 70 years old and will probably be given emeritus status.
