BioShock 4 may arrive in 2022, according to a leak sourced from an Nvidia data base. The leak, which included a list of supposedly upcoming PC releases, included an entry for BioShock 2022, kicking off speculation that the game could arrive as early as next year.

Although Nvidia has confirmed the list itself is genuine, it also said that some of the titles on it were merely speculative — which is to say, not in development, or imminently releasing, to the best of the company's knowledge. It did not say which titles were speculative and which were genuinely in development.
2K Games, which owns the BioShock property, announced the fourth BioShock game was in development in 2019. At the time, 2K president David Ismailer said the game would be in development for "the next several years." That timeline could line up with a 2022 release, but it was also shared in a pre-COVID-19 world. Disruptions in workflow caused by the pandemic likely extended development time on the game, potentially pushing it out of 2022 — if it were ever set for that year at all.
This fourth BioShock would be the first in the series to be released since 2013's BioShock Infinite, and the first to be developed by Cloud Chamber Studio since Ken Levine dissolved Irrational Games. Cloud Chamber Studio is headed up by Kelley Gilmore, whose decades of experience in the industry were spent in part on the Sid Meier's Civilization and XCOM series at Firaxis Games.
To date, we've heard nothing about the game's setting, story, or just about anything else.
