"Dedicated to a single game" my shiny metal *radio edit*
Previous years have had a single-game Direct in August: although we'll get such a Direct this year, it won't have a game focus at all.
Nintendo has announced a "Nintendo Museum Direct" will air tomorrow at 3 p.m. PT / 6 p.m. ET / 2300 CET. The ten minute show will feature a tour of the new museum in Kyoto all about Nintendo history ahead of its opening this fall.
