Considering how much I love Koto's 1/6 Man of Steel (Youtube Review here:
https://www.youtube.com/watch?v=wk0ZK7y5EHg), if they do any non-armored characters (Cap, Thor, Hulk, etc.) I will be pleasantly surprised.
And by pleasantly, I mean I'll go bat-crap crazy with glee!
No one seems to be doing 1/6 scale movie statues, which is my preference. This would put Koto out there with no competition. Sure, Hot Toys has their figures, but I'm a statue collector. This could be HUGE if they put out quality pieces in this scale.
Or... we get more Iron Man armor... and maybe an Ultron.
And no, I would not turn down Ultron or the Hulkbuster armor if they put it out. In fact, I'd celebrate those as well.
Moral of the story: This is probably a win no matter what.
