What was rumored is now confirmed: The revDSG will be applied to the September 1, 2023 (2023, not 2022) will be put into force. Formally, this will be decided by the Federal Council later this year, but the Federal Office of Justice (FOJ) informed accordingly today on March 3, 2022:

Originally intended to come into force in mid-2022, it was later said that January 1, 2023 would be the latest date. This delay serves neither the reputation of the legislative process, which was disappointing overall, nor the acceptance of data protection in companies, which have to constantly adapt to new deadlines.
However, this was probably done in response to the concerns of the business community – or, to be more precise, a section of the business community – to create an informal transition period by enacting the revDSG at a later date. Another reason was probably the resistance to the unsuccessful draft of the revised VDSG with the associated follow-up work (assuming the administration can muster the strength to revise the draft as fundamentally as would be necessary).
