I will note that out side of a possible cameo in Golden Keys (like damn that was the least exciting blurb for a hard cover ever), that the most likely tie in product for the movie would be Edgin's Guide to the Forgotten Realms (One D&D Campaign Setting Book), with little post-it comments from Edgin the Bard with quips from Holga or someone else.
I mean between various 5e hard covers, the Drow changes being covered hy RA Salvator novels, the upcoming movie + tie in novels (including a new Lord of Neverwinter), and a new edition with tradition being FR gets a setting book and Ray Winningers hint of a setting revisit for 2024, and fans of FR begging for years for stuff outside getting better covered then what was in the SCAG this could be the prime book to feature the movie characters on the cover and in the name.
