If you look at the way preorders seem to get out out, there is a loose pattern there. A big chunk of marvel, interspersed with as much or a little less Star Wars, and then a handful of DC or "other" (BTTF, Cyberpunk, IT, Hellboy, Alita etc). That pattern seems to hold going back at least 2 years. The most recent "others" were BTTF. If I had to guess, they'll announce something DC (likely Nightwing, maybe new Harley if old ones ship) to hold us over until the barrage of No way home and maybe eternals and the new Boba Fett show. Then we'll see how serious they were about the Black Adam/Flash etc.
And yeah, I'd be very surprised about villain's, even Marvel see's them rarely, unless it's an independently popular character.
