Found my answer: >>> The exact release time of games on the Nintendo eShop is decided by the publisher and may vary depending on the title. General release times are listed below, but they may not apply for all game releases.
Digital-only software will usually be available at 9:00 a.m. Pacific Time on the day of release.
Digital software that is also sold physically will usually be available at 9:00 p.m. PT the night before the physical game's release date.
Some third-party titles are not available until 12:00 p.m. PT on the game’s release date.
New digital content is generally added to the Nintendo eShop each Thursday.
DLC for games is not added at a regular cadence. For questions about specific DLC release timing, please check the specific details for that game or verify with the game publisher. So prob in 30 minutes
