I'm really not crazy about this armor. Wasn't when IM3 came out and still not crazy about it in AOU. I know a lot of fans seem to like it. I do like the new colors better though as I never really understood the color scheme of MK42. As one of the miscellaneous house protocol armors fine, but not as Stark's main armor. Then again it was a prototype in IM3 so the MK43 is probably the way it would've looked had he finished it. I only own MK2, MK3BD, MK7 & MK7BD, & MK33 (big fan of the silver centurion armor from the comics). I also own War Machine MK1. I missed out on MK4 the only other armor I was interested in buying but lack of Stark face sculpt inside helmet option made me pass. If they redo it in Die-cast I may break down and pick it up. Still considering MK17 Heartbreaker (hoping maybe he'll still be around for discounts next year). I was interested in hulkbuster (MK44?) but will probably be too expensive for my tastes. I was hoping I'd be able to get by without buying any new Iron Man armors for awhile, but if there is a MK44 I'll have to wait and see.... ugh.
