We've reached 32 participants signed up, but I'll still leave sign up open and if there are sufficient people who signed up, I will make another round before Ro32 similar to last season, where everyone go into 8 groups and play round robin from there.
Also, to finally address the promotion incentive thing, I understand that Blizzard will make their league distribution change soon. Like I said, I will see how it goes, and if Blizzard screws this up I guess I'll have to remove the incentive thingy. If it's just 2-3 people who promote (like what I actually expected of previous seasons), then I'm fine with going ahead with the incentive.
