Well, as far as we know, they aren't done with the Iron Man line yet, right? I wouldn't expect to see an Obadiah or Pepper, but Iron Monger is a strong possibility, though the figure would be huge! As far as variants go, MK1 is massively different than any of the others, so I don't think that it counts as a variant. As for Batman, Scarecrow would be cool, but I think I would rather see the Liam Neeson character (Raas al ghul?) made. They dont seem to like to make characters that are not very flashy, I mean, how boring would an Alfred figure be? or Fox? or Gordon? In the end, HT will do what they think will earn them the most money, and my guess is that their research into these other characters has shown that there is not enough nterest to support a high end, espensive figure. Something that may not be true of Star Wars.
