In my mind, the three originals on the new spec map couldn't exactly carry the event on their own. BJ is a no, and while Hill House and the Billie Eilish tagline are the best bets marketing wise, even then they aren't quite A+ material without a big name IP to carry them through.
That, along with the fact that Legacy is keeping the info on the down low (which I am very thankful for, secrets fuel speculation), makes me think we could be in for a big surprise whenever Uni decides to announce the lineup. Hopefully that surprise isn't squandered early like Us was last year, but I do think there is room for a little excitement at the idea.
