I feel like they would've explicitly stated that to be the case if they were going that route. I'm not super familiar with D&D, my only significant exposure to it was Honor Among Thieves, but one of the biggest strengths of the IP seems to be its adaptability to different mediums due to its open-ended nature. It consists of a very expansive collect of characters, creatures, and locations, so I imagine they'll use whatever they feel is most well-suited for the event.
