It's too early to defend or to criticize the new miniatures effort from Wizards. The proof is in how the game and the miniatures are received.
If we're right, the new line will
bring new people into the leagues and tournaments,
reach lots of D&D players who aren't modelers,
support a secondary market that allows players to sell off the miniatures they don't want and hand-pick the ones they do,
and revitalize D&D skirmish gaming (and more).
But the proof is in the results, and we're not going to see those results for a while yet.
