I hope they win a sizeable settlement and use it to self publish their original vision.
Except they can't.
The magicians that live near the ocean own the copyrights for essentially all that you would actually recognize as Dragonlance. That's the reason no new Dragonlance novels from W&H came for the longest time, there was no licensing agreement.
Even if they win (or get the desired settlement) they still won't be able to publish anything as Dragonlance without the say-so of the magicians that live near the ocean (which will not be forthcoming, as you might imagine).
Note that the first novel is totally done, the second one was already submitted as a draft...but those books will never see the light of day.
unless the goal is a negotiated buy-out of the IP.
I consulted a highly sophisticated future-divining machine (pictured here

After some time, the machine returned the following answer:
"Fuck no."
I had previously understood DL as an IP was owned by W&H, but TSR had bought the rights to use the IP.
It's the exact opposite. The Magicians own the IP, W&H licensed it whenever they wrote for it.
Part of the language of the filing is exactly explaining that the nature of the deal was such that whatever time and effort W&H dedicated to the project (time and effort which they obviously did dedicate, since they fully wrote one book and drafted the second) was essentially "locked-in" with the Magicians, since it's all Dragonlance material which W&H CANNOT publish under any other guise than an official Magicians publication.
The fact that the Magicians knew this, and knew that W&H's contract with their publisher was also completely dependant on this licensing is what gives rise to the tortious interference claim. The Magicians knowingly fucked over W&H's contract with their publisher by having them write a set of novels that they could only ever publish with consent from the Magicians. Once the Magicians refused any further drafts, they boned (proper legalese here) both W&H AND their publisher.
