There's still no western release date for Yakuza: Like a Dragon, but we now have a pretty good indicator that Sega is gearing up for an announcement. The ESRB has rated the new title from Ryu Ga Gotoku, assigning it an M for Mature rating.
You can find the official rating over on the ESRB website (which was first noticed earlier today by Gematsu). Yakuza: Like a Dragon has been rated M, which shouldn't really come as any great surprise considering the seedy underbelly of Tokyo that the series so frequently examines. Like a Dragon will continue adventuring around the crime-riddled streets of Tokyo and Osaka, adding in the new location of Yokohama for the first time in the series.
As you can see from the official rating, Like a Dragon has been rated for the PC, PS4, Xbox One, and Xbox Series X. There's no mention of a PlayStation 5 version of the game because it's yet to be announced by Sony or Sega (although it's hard to imagine the game not coming to the PS5 eventually).
This could all point to Sega gearing up to announce a western release date for Yakuza: Like a Dragon. For some context, Cyberpunk 2077 was rated by the ESRB back in May, when it still had a release date of September. If Yakuza: Like a Dragon is still targeting a 2020 release date for the west (and there's been no indication from Sega that this has changed), it's likely launching toward the very end of the year.
When it does eventually launch, Yakuza: Like a Dragon will be arriving on the PC, PS4, Xbox One, and Xbox Series X. It'll be a day one launch title for the Xbox Series X, and is part of Microsoft's Smart Delivery program, giving those who purchase on the Xbox One a free upgrade to the Xbox Series X version.
