Bioware has been courting the Destiny community with this game. There are lots of famous Destiny streamers who are credited in Anthem. They know what we want. The fact that they aren't coming out saying they have it indicates they don't actually have what we want. The most reasonable thing to think about Cataclysms is that they are hard public events that appear in Freeplay. If it's not new dungeons or other content, what else can it be?
Occam's razor rarely, if ever, fails.
