It might need to be a fair bit after the 20th if they want any clear air. I'm personally very pessimistic about what we'll see when WotC unveils the new OGL, and there's a lot of people who are primed to be angrier than me (not to mention those who've glommed onto the whole business for outrage clicks and who have an interest in keeping it going as long as possible)
But still, even before this whole OGL business blew up in everyone's face, Golden Vault info was still way behind the regular preview schedule. I just did an archive search, and it looks like we had page counts, cover art, a few internal images etc, and content details for Spelljammer in April 2022, four months before the release date. If Golden Vault was on that timeline, we should have seen the cover art in October.
