As of now, there is not much known about when the game release or when From Software will release the game.
From fans trying some black magic to make From Software release the game to making the game trend on Twitter, the Soulsborne community seems to be trying everything to make the game release.
From Software eventually released a statement debunking such rumors and stating that the game was indeed in development.
The game was announced back at E3 2019, but we heard pretty much nothing about the game after the initial announcement.
