I will try to be more succinct:

What 3E products were licensed, but not printed, by WotC.

Besides the obvious books, and online articles, what else did WotC publish for 3E (i.e. 3E Diablo, game day modules etc.)?

What is the licensing/"official" status of the following:

  1. 3E Dragonlance books besides the campaign setting book.
  2. 3E Kalamar books.
  3. 3E Ravenloft books.
