Wyrd announced that there would be various Wyrd events (including Malifaux 3ed) at Gen Con. So far, I see no events listed. Are these going to be ticketed events or just show up on the hour to try?

Any demos/games at their booth won't be listed as events.

If they are planning for actual ticketed events, they may not have gotten them in on time to be ready for registration tomorrow.  Events will keep getting added until nearly the start of the con.
