Microsoft have updated the release model for Windows Server 2022. There will no longer be a Semi-Annual Channel, instead there will only be the Long Term Servicing Channel (LTSC). A new version of the LTSC will be released every 2-3 years, and each release will receive 10 years of support – 5 mainstream + 5 extended.
They state the focus of the Semi-Annual Channel was innovation around containers and microservices and that this work will continue within Azure Stack HCI instead.
