Does anyone know when the VEX worlds waitlist results come out?

I would suspect no one knows for sure outside the RECF. Even if you consider how they did it last year, that situation is very different than this year.

I expect Mr. Mantz to be issuing a statement about the virus situation this year shortly - meaning by mid-march (when official qualifiers are complete and the full swing filling of Worlds is happening). A lot can happen in the coming two weeks.
