I would say the number of minis that you bought is quite small (only a hundred or so by the looks of it). If WotC are trying to target that sort of gamer with their DDM's I think that they are going to fail as the sales numbers will just be too low.
So I would say that you are not in their target market for DDM.

Actually, he sort of is - it's just that he's part of a very large group of people who buy only one or two packs from a set. You can make a nice profit from those people.
The point is with DDM is that it caters for quite a large array of people; who it doesn't cater for are those who want to know exactly what they're getting.
Cheers!
