While the release date for the West has not even been confirmed, there seems to be a possibility that the new one Yakuza: Like a Dragon is not exclusive to PlayStation 4, but that it will arrive also on PC via the Steam platform. The fact was discovered by the user Wario64 of Steam DB, a site through which it is possible to notice that the new title of SEGA has the ID 1235140. To remove any doubt as to what title it was however the presence of the cover (otherwise it could have been any title).
However, remember that even if the title is there, this fact is not to be taken as one official communication by the software house, which has not yet announced when Yakuza: Like a Dragon will be released in the west. Also, you have to consider the fact that although Steam DB reviews many games on the Valve platform, its accuracy it is absolutely not one hundred percent. The fact is that the loss of the exclusivity of the Sony-branded console could happen, especially once you get to the west, where the PC market thrives along with the console one.
For now, there is nothing left but wait for official communications by SEGA, although it must be said that it would be a real shame not to bring the seventh chapter of the saga to the West, given all the remastered that are available both on console and on PC.
