@lamp yes and no.
Yes, #Apple will #EoL the #Intel-based "Cheesegrater" #MacPro by 2029-2030 as per their preannounced platform lifecycle of 10 years.
No, because #Apple's #ARMv8.1-A - based #SoC's are heavily modified in that they require a feckton of custom chips solely for the purpose of #ReducedLifecycle and making repairs harder if not impossible to facilitate...
Unlike their #amd64 / #EM64T - predecessors they don't have a dedicaded #EFI chip with "#BridgeOS" aka. #AEFI aka. #macOS - #Recovery on but use the exact same #Flash chips that are #RAID0 as #SSD, and since those are custom with their own controllers ( based off info from @marcan ) - basically every chip is it's own NVMe but proprietary...
And when (not if) they (inevitably) die (due to exceeding TBW lifecycle or terrible engineering frying them with 12V on a 2,7V rail ), the entire system is braindead.
And that is not by accident but rather intentional...
