I received the following announcement from the FamilySearch Newsroom:

Oaks, as the keynote speakers at Family Discovery Day at 1:00 p.m. MST on Saturday, March 3, 2018. They will share insights from their family experience in family history work, the importance of individual families and family connections, the corresponding importance of temples and temple work, and insights into how each person can contribute to family history based on their circumstances.
