Yup, you’re right. I’m working on it. Here’s the problem:
The miniature path is close to 18 months to go from concept to your FLGS’s shelf. The path for getting a module from concept to your FLGS’s shelf is a lot shorter. Skalmad was put into the pipeline before the module was written — all that existed was a name for the module.
This is the biggest issue that the miniatures have as an RPG supplement. Take Dragonborn, for example — to have miniatures coincide with the release of 4th edition, they needed to start down the miniature pipeline months before the concept art was even finished! We had three proto-draconborn slated for Dungeons of Dread that ended getting cut because it didn’t match the concept art for the race.
We’re trying to reduce the time to go from concept to market with these miniatures, but for now it’s a very difficult problem.
That isn’t pre-painted, but colored plastic.
The end result is a much more monochromatic set.
