There's no word on when the country will get the mobile version, but it's not launching there alongside the others.
Vietnam is also part of the list, but only for the PC open beta. Though we don't have a complete list of Diablo Immortal server regions just yet, the recent roadmap has at least confirmed that the following regions will have "dedicated game servers" to reduce ping and improve general connectivity: The timer above relates to everywhere but the Asia Pacific regions listed below, where the release date is June 22 instead. Players are advised to pre-register on iOS and Android so they can get access to the game as soon as it comes out. The reason these two sizes differ so much is because of the platforms. However, players will be able to sign up to an open beta for PC if they are interested. As for the PC port of the game, during the preload for the beta of the game, Diablo Immortal’s install size is 27 GB. It will release on iOS and Android first before coming to PC. The game will be available on PC and Mobile. It will retain full crossplay and cross-save features with the mobile version at this time, however, and any Diablo Immortal progress made on the PC will, thus, not be wiped once it moves out of this ceremonial open beta state. Even with the tweaks already implemented for PC, Diablo Immortal still provides a smoother experience on a mobile device, with the screen size currently is the only reason to give it a go on PC.
