rumors are trickling down at both Yale & Harvard that they might delay the start of next semester, basically offsetting AY2020-21 so that the fall semester would take place in SP21 and the spring semester in SU21. I've heard that this is a 50/50 possibility...

needless to say, Ivy & peer universities would coordinate on any decision like this, so as to prevent admits with multiple offers from enrolling at the competitor school that stays open for FL20
