The Batman variant is $430 so I wouldn't doubt at least Aquaman and Flash at $430. Prices are crazy, so for me that means more cuts to my list, because I do keep a list.
I'm still in for Aquaman as I always have been, pending the full reveal. Flash is also on my list. Darkseid would be cool to own but he isn't on my list. He's a central villain so I thought about it, but he's not as important to me personally. The Batman villains are so I'd rather wait for Penguin, Two-Face, Ra's, Riddler, etc. and Deathstroke. Really limiting things and sticking to my character list.
