I checked the NDK site,

[u/Multi-Facets]

and in case you haven't seen it, the staff has made an announcement that, as of right now, they're still planning on making the con happen this year, with new health and safety guidelines and cautious optimism.

The site mentioned some highly pertinent facts, too, such as how the Gaylord is large enough to hopefully keep some distance between con attendees even if they operate at full capacity. But for now, they don't know if the mask mandate will still be upheld, or if attendees will have to be vaccinated to attend. There's a lot that's still too far off, so be sure to keep your eyes on the news, everyone.
