Not really. WotC approved all of it -- until they had a PR bomb go off with hiring practices within WotC on the M:TG side, contracting with a nutbar Qanon artist, and otherwise with their racial depiction of drow within D&D. It had nothing to do with DragonLance. But by that time, they had already approved Dragons of Deceit. WotC apparently did not want to unapprove it and make further changes -- instead, they wanted to prevent it from being published for all time.
That's one interpretation of events. But as I recall, the lawsuit itself says that WotC objected to elements of the proposed story and, after going back and forth several times with Weis/Hickman, apparently gave up on the process. The lawsuit was to get WotC to pay up or restart the process, which is what it accomplished.
The "oh, the problem was actually the drow" is speculation by folks that don't want any fault to land on Weis or Hickman.
Together with the press release which confirms the subject matter and characters of the new novels are the original characters, it is plain and obvious that the subject matter of the trilogy is the War of the Lance and that the forthcoming trilogy will be the Second Lost Chronicles, to be published by Del-Rey. That isn't really speculation. That looks balls on accurate to me.
I remember when November's book was "definitely" going to be Dragonlance, too, and that there was
no way that Strixhaven was going to be a D&D setting this year. (Both arguments have been made here since January, often quite vehemently.)
The part I find remarkable on this is that WotC decided that the content of these novels was so harmful to their reputation that they would rather they never, ever came out. The only thing I can think of which would merit drowning of the DragonLance baby in the bathtub for negative PR has to be the ongoing inclusion of Goldmoon and Riverwind in Dragons of Deceit's approved storyline. I can't think of anything else which would have caused them to want to otherwise pump the brakes on the whole thing.
Gully dwarves say hello.
Dragonlance has a
lot of stuff that would never be part of a WotC setting released for the first time in WotC. Deciding that none of
that stuff is the problem is dancing past a lot of pre-existing issues with the brand.
So, I don't get it. I guess WotC decided there wasn't really enough money left to make on DragonLance. At least, not enough to be worth the negative PR. If they thought there was, they'd publish the books themselves. Instead, they licensed out the novels to W&H to flog on their own at Del-Rey.
If your argument is a bunch of suppositions based on your other suppositions based on still other suppositions, it's going to be hard to correctly reverse-engineer WotC's thought processes.
The only thing we know for sure is that WotC doesn't think Dragonlance is a money maker for them, given that they've never published any game material for it themselves. They've obviously considered it, including for this edition, with the D&D Next Kender. (No one knows when Joe Mangionello's alleged playtest draconians were created, so it's not evidence of any Dragonlance plans later than D&D Next unless we get some concrete details, not supposition, that clarify things.)
