Is there a list of companies that will not be attending this year? I see that Steve Jackson Games is not on the map...

This is complicated since 2021 was a smaller show, and there's been considerable change since 2019.

I only noted that Onyx Path (RPG) and Board Game Geek were notably missing along with SJG pulling out.  But even then, Onxy Path stuff will likely be available at the IPR booth, and BGG has stated their products will be available at "partner" booths.
