hang on for a second....
If we're talking Dragonlance, we should recognize that DL was developed initially by a different company, and with a different intention than Wizards.
I mean lets face it, TSR was a one trick pony, they sold D&D and thats it. Sure they dabbled with a romantic choose your own adventure line and novels based on games but the desired result was always the same, ... sell D&D.
Now as I see it Wizards has a different motivation, because wizards is really Hasbro. Selling D&D is certainly an expectation, but far from the only one, they can afford to publish books for books sake, because they want as big a market as possible for dozens of products. I also see them wanting the best products possible as well because good products have good longevity. A lot of the old D&D hallmarks are gone,... Wizards doesnt really make premade adventure modules for example, and while I think there is a Dragonlance game, there isnt much of a tie in to the novels any more. Even though the new Wizards churns out books, the products are better and more consistent than TSR, and that goes to almost everything they put their stamp on.
Sure they miss occasionally, sometimes books based on games (or vice versa) become fannish and amateur but I honestly think wizards is trying to avoid that.
Thats just my 2 cents of course but still.
