Based on how King's Fall took to be made and Luke Smith's discussions on the creative process behind Raids and their dev time, there's a very high chance that we won't see a Raid until Forge of the Gods and that Vex Void will have a Vex Arena, and not a Vex Raid. I'm personally fine with it, but thought this probability should be brought up and addressed so people don't flip their shit when Vex Void is finally announced.
