BYU Studies has an excellent article on the commemoration that year of the 100th anniversary of Moroni's first visit to Joseph Smith. I posted comments about it on my new blog, where I am accumulating everything relevant to Cumorah.
The question to consider: What will the 200th anniversary be like?
Unless there is a course-correction to the current trend, in 2023 any celebration at the "hill in New York" will involve only the set of plates Joseph obtained from Moroni's stone box on the hill. There will be no mention of Jaredites or Nephites having lived in that area.
