Cast changes due to BrodadwayCon?

A friend and I were planning to head to the city this Saturday to see some shows, and then my daughter reminded me that it's BroadwayCon weekend. Do you think there will be fewer principals performing if they are involved in the convention? I haven't seen a complete list of participants so I'm not even sure which shows might be affected. I'm thinking maybe we should just wait a week to avoid the craziness.

I could never see an actor putting BroadwayCon before his or her show. Don't worry, go and enjoy.
