Because this whole thing will be over at some point next year when either: 1) vaccine is widely available; or 2) everyone has already caught it
Vaccine IS coming, just don't know for sure when. I personally think a dependable, safe vaccine will be made by the end of this year. Others think it will take longer etc.
But regardless, can delay the movie till next year, or 2022, whenever doesn't really matter tbh. My point is the same .
