It appears that the PlayStation Twitter account may have jumped the gun, but in a now deleted tweet the news was confirmed that Dark Souls III’s first major DLC, Ashes Of Ariandel, will be released on October 25th. The annoucement has already been made in Japan via the likes of Famitsu, where a season pass has also been confirmed which will contain Ashes Of Ariandel and a second expansion.
Not much is known about Ashes Of Ariandel except that it will contain a new PvP map called Immortal Arena, and that the setting looks to be snow covered. There will be new weapons and armour to adorn too. A trailer and more details about Ashes Of Ariandel is expected in the next 24 hours.
