All devices - official as well as community will get the latest OS build possible. For some an A16 may not be possible. For such devices it would be the next lower level possible. For example, if A16 is not possible then it would be A15. Official builds get OTA OS upgrades which take time as the changes need to be seamless and avoid data loss. Both Pixel 8 shiba and cmf 1 will get the OTA update. The ETA is the unknown factor at this time. Will share dates once I get them from the developers.
