For those that are wondering, Origins was using a date about 6 weeks out from the start of their convention. Using that information it would be mid-June before Gencon would make a go/no go announcement. That is still another 6 weeks from now. In between now and then states stay at home orders are tentatively expected to expire. There will be enough time between those expire orders and and a decision to allow scientists to see if we have a bounce back of cases or they continue to decline.
Right now I'm still making my plans as if it is going to happen (adding to it are preparing things i'll need to keep myself safe). If its cancelled, I'll still need those things to protect myself. Airlines are not charging to rebook or refund so there isn't too great a risk there.
Until states (as the federal government has taken a hands off approach) issue guidelines on events Gencon really has to take a wait and see approach.
