PSAT 2020 Cancelled: Entrance to National Merit via SAT?

Dates for this years PSAT are 10/14, 10/17 and 10/29. I don’t think they can move the dates beyond that. If they allow the SAT to be considered ( which is feasible given it’s 2020 and anything can happen), I think it will really throw a wrench in things. Will they allow the student’s highest scores to be used? Spring scores ( where kids get an extra couple of months to prepare?), Winter ( lots of Covid issues).
I’m hoping they stick to original dates. Why don’t they add more schools to space kids out?
