I think the general consensus among fans is that this is their chance to own the Mark I without paying sky high prices.
I'm not sure that many will care about the differences
My only concern is the price, which is silly considering the eBay prices, but Hot Toys know that they have folk over a barrel so they could put a hefty tag on this and still see plenty of sales
I suppose it is a rather complicated figure, as said in different threads, the most expensive part of a Hot Toys figure seems to b the head, at least on the aftermarket, but the Iron Man figures I would say are an exception to that.
We'll see soon
