And this time the translations will be published by WotC itself. This means sales in no-English-speaker markets.
OK, we can agree D&D is a leviathan within TTRPG market but a little fish for the videogame indstruy, but important videogame franchises started with relatively humble titles. And BG3 has helped a lot to open new doors.
Other point is D&D multiverse allows total creative freedom to try revival or reimagination of forgotten IPs. For example Glow worm, a preschool toy, could be recycled like a new domain of delight in a hipotetical future Witchlight setting. (And later to be sold like backpacks in Fortnite). A spin-off of my little pony also could be a domain of delight.
Other companies from the entertaiment industry could try D&D like a jumping plataform to revitalize "old glories" or promote their own franchises (for example a new manga serie) in the Western market.
D&D is not only about throwing dices and calculating hit points. Even when a solo person is creating her homemade setting she is also playing D&D in other way. Some players are interested into showing their own ideas and creations, and WotC should offer the right digital tools.
* One of the next necessary steps by WotC is an update of d20 Modern. Or Everyday Heroes by Evil Genius Games to be "licenced" int D&D-Beyond (if they are publishing more books this should mean their sales are good).
