I have Iron Man on preorder, I don't really care for Wolverine or Spider Man but I could consider to pick them up 'cause I'm quite sure that with ultra low ES they will acquire value, so I can get some finances for my other purchases. I like the idea of Iron Man alone but I'd also keep a few other characters, like Dr Doom, Juggernaut, Thanos, Apocalypse.
What most people don't seem to get is that the cold cast process has usually an incredible quality and imho is far, far better than painted, not only 'cause you can avoid the painting issues, but also 'cause it gives a much more mature display to the final product. It's probably just me but I can't stand how cartoonish look many statues, that's why I find 10x better the new Punisher PF in comparison to the comiquette or the old PF.
