I think the Ironman is kind of like a museum pose, just a flying museum pose. I would bet there will be a deluxe with one of the options being a Stark Gauntlet snap, which gets you closer to that museum type pose. I've got Deluxe Thanos, Cap and Thor on pre-order and definitely adding Tony when he goes up...
damn if they add the infinity gauntlet to the IM, I'm gonna have to break my original thought process of passing on him
