I feel like with airfare, hotels, and shows possibly at a deep discount, you'll have some people from all over the world who won't be ale to resist a good deal. Will it be a lot less than what NYC usually is used to? Sure. But, you still may get a decent amount of tourism when Broadway reopens and NY is deemed "safe" by the powers that be.
