This has turned up in a few Wizards’ blogs recently, such as Stephen Schubert’s:
We’ve started searching for another Associate Designer to add to the RPG/Minis design team. We’re looking for an applicant with some amount of understanding and excitement for the D&D miniatures game, so that some of this person’s time can be spent working on that game, as well as mechanics design for the D&D game, too. If you’ve every had an inkling to work on D&D, now’s the time to throw your hat in.

In other news, we’re close to starting the All-Stars selection process for the D&D Minis game. Through this process, we’ll be culling a few hundred minis from earlier sets down to 60 or so, and then we’ll provide updated stats for those minis so they can be used in the new D&D Miniatures game that comes out next year.
