This is not exactly news as this is being for quite a while now and the code artifacts have been visible as well. But given Apple's experience with their A-series CPUs it could make strategic sense although it might certainly hurt them on many ends, e.g. possible loss of Bootcamp functionality, inefficient virtualization for VMware or Parallels, loss of many old and loved / needed but unmaintained applications, maybe issues with Docker (?). Not sure that the developer community (one of their key target audiences) would love to digest this at this point in time (possibly later). We have had this issue already when Apple made the switch from Motorola's 68k to Intel. So I would give it a 50% likelihood for a switch in the next 12 months but not more at this time.
