According to billbil-kun, Diablo 4 is set to be released in the middle of September on Switch 2. This also suggests the physical version won't include a Game-Key Card, removing the customer's ability to re-sell the game. Billbil-kun also revealed the Switch 2 version of Diablo 4 will cost £63 / $70 / €70. Given how close we are to the leaked release date, when can we expect an official announcement? The show takes place 12th-13th September, and given the leaked release dates, the developer could be planning a shadow-drop-style announcement to kick off the event.
