So insanely true. Today's "MUST HAVE AT ALL COSTS" is tomorrow's "meh." Does anyone really care about the "grails" of yesteryear? Grey Hulk Diorama, Exclusive Doom PF, Hot Toys Mk VI Promo Avenger. Every once in a while someone will post a display that includes old figures/PF's and someone will go "oh you got the Green Hulk PF from a while back, neat, I always did like that one" and its just no big deal.
There will be future Iron Mans from IM3, IM4, Avengers 2, etc., that will diminish this new exclusive in time. Heck this figure doesn't even have screen accurate battle scars so the door is still open for a 2.0 (with correct face scratches, die cast parts, etc.) Its all about perspective.
Years ago I was frantically calling Sideshow from work to secure an order for an exclusive ROTS Anakin (which I think came with a tiny hologram or something.) I was quite stressed about it. How silly to think back. I sold that dumb lipstick Anakin years ago and have HT's badass Bespin Luke on display now.
