Update (July 16) - Bandai Namco Entertainment Southeast Asia has published the official English trailer for SD Gundam G Generation Cross Rays, confirming that the English localization due for release in Southeast Asia will be available on November 28, the same day as the Japanese release.
Although the English announcement lacks the Premium G Sound Edition, it confirms that the early purchase bonuses will come in the same complete set that Japan gets, including the port of SD Gundam G Generation Monoeye Gundams for PlayStation 4 or Nintendo Switch - although it may seem like this port may still be only available in Japanese language.
You can watch the official English trailer right below, and the original article follows afterward.
Original (July 11) - Bandai Namco has finally confirmed the release date for SD Gundam G Generation Cross Rays in Japan, where it will be available on November 28. This announcement is made by publishing the second major promotional trailer which shows a montage of battle scenes, as well as a rundown of gameplay features that have been known so far, including the new Raid Group and Ability Get features.
Just like the recent Super Robot Wars games, G Generation Cross Rays will have a limited Premium G Sound Edition containing in-game loops of original anime theme songs that will be available only in Japan. Early copies of this game will also come with bonuses such as extra option parts, the Titans-colored Sisquiede from Monoeye Gundams added to the production list, and a port of SD Gundam G Generation: Monoeye Gundams, a classic game originally available at Bandai's own WonderSwan Color. The latter will be only available on the PS4 and Switch.
SD Gundam G Generation Cross Rays will be released for PlayStation 4, Nintendo Switch, and PC via Steam in Japan on November 28. Although a Western localization has not been announced, this game will also be available in the rest of Asia, with an official English localization confirmed coming to Southeast Asia.
