I checked with Jacob - the 07/01/2021 OverCluck Event is not the release date for the Z590 Dark.. Vince will be using a Z590 Dark to overclock on, but the notify queue is not opening that day. Don't have an exact date, but it's not as soon as 07/01/2021. Sorry to disappoint.
If not 7/1 hopefully very, very soon after. I finally got a GPU order in, never thought I'd be waiting on a motherboard to finish my build!
Also... would be nice if there wasn't a feeding frenzy for 10 boards upon release
