I think the article was a nice primer for a future product. Just enough to whet the appetite. I'd hate to run a game just on the info provided.
A few scant details and a couple of advanced classes does not a mini-game make.
If you want to run D*M, take the advice of the article: Go get the original campaign book. It is an aboslute must have for an D*M themed game. For me, I'm using a modified version of the CoC magic and sanity system, and so far it seems to be working out.
Overall though, I think Dungeon/Poly issue 108 was the best in some time.
