Keep in mind the plastic Mark 7 comes with awesome battle damaged parts which would not be available in the die cast version. Battle damage is best represented in plastic.
Uhhhhh.. why wouldn't it have BD parts? Lot's of the recent HT IM figures have BD parts. The Mark VII is so appreciated by the community that I think it's a prime a prime candidate for Hot Toys to go all in on if (when) they decide to drop the DC7.
