One of the reasons I expect to see something out of Dragonlance eventually is how Ravenloft is now being presented, as not just a world but a toolset on how to run different forms of horror in fantasy. As enunciated in the DMG, Dragonlance is D&D’s epic/romantic fantasy setting, the sort of world whose story rules would apply to campaigning in a Round Table or Chansons de Roland campaign. Combine that with an avenue for finally presenting mass battle rules for 5e, and the actual world-specific plot and character widgets are gravy for designing a Dragonlance book à la Van Richten’s Guide.
