I interviewed Jeremy Crawford at Gen Con, and he said that they are more focused on PAX, and have pulled out of Gen Con.
Saying Gen Con is for playing games. So Baldman games LLC is the only D&D representative at Gen Con now. WotC staff show up, but not to promote or do panel discussions.
I took pictures of those cards that were handed out while at Gen Con. And I plan to make good quality scans, if anyone would like them for printing purposes.
