To be honest, I think the Mark 1 2.0 is by far one of the best armors they have done so I wouldn't feel compelled to get a new one just because it's in die-cast. I love die-cast, but when you're already spending $250+ on figures alone, adding die-cast to drive up the price isn't really worth it imo. To me, I can't really tell the difference between a figure that is die-cast and one that isn't unless I'm holding it. Since these are figures that sit in my display case and only get re-posed once in awhile, I'll pass on spending the extra money. Leave die-cast to figures like Transformers where at least they would get handled more.
I totally agree but maybe I'm just biased since I recently picked up Mark 1. But it's an insanely great figure as is that really doesn't need die cast. As is I think it's my favorite IM figure and I have the 42 and IP. Die cast does not necessarily mean better figure!
