Oh yeah. I still want to get my hands on an Iron Man 1:1 too...I was thinking it would be neat if they offered a War Machine 1:1, but not sure how they'd pull it off....only differences are the paint job and red eyes right?
There is additional armor on the shoulders, helmet and chest including the machine gun on the back. So it would be much larger than the MK III because War Machine is basically a Pimped out MK II armor.
