As for the exact things Swen said, that the original poster referred to, I think it comes from this intereview.
Cheers for sharing that. I notice the interview doesn’t actually say that the secret won’t be revealed until full release, only that it’s about the full release and hasn’t been revealed yet. That does potentially change things, and mean that it could be something that’s not necessarily a spoiler, like a mechanic.
And in that case, I have no idea what it might be!
