Out of nowhere, Nintendo has dropped a new trailer for Fire Emblem Warriors: Three Hopes, which releases on 24th June 2022.
A full analysis of the trailer from us will be coming later.
Amusingly, it seems the earlier Amazon Japan screenshots (which were taken down) originate from this trailer. Presumably, those screenshots were meant to be added after the trailer.
Update: Japanese trailer can be viewed here.
Additionally, the Japanese website has been updated with the new information from the trailer.
Besides that, the Japanese Twitter has shared profiles for the protagonist and their Sothis counterpart.
