the Governing Body just announced that they're canceling the assemblies in 2022 as well, aiming to restart in 2023.
The actual announcement is that special conventions are on hold until 2023. No announcement has been made about "normal" regional conventions or circuit assemblies.
"Special conventions" are those mega-sized international do-ups that feature talent shows by JWs, special field service arrangements for delegates, overpriced airfare & hotel arrangements for delegates, etc.
