From my understanding, the event will either happen when/where it's supposed to or it will not happen at all. That is dependent upon decisions made by the North Carolina governor's office. I have not heard of any contingency plans involving an alternate site.
Super32 announced today that the event will not be in North Carolina due to the COVID related policies in that state. They did state they were working with alternate locations for a venue and hoping to have a potential announcement on that front soon (i.e. if there will be an event, where it will be).
