Both PPC->x86 and x86->x86_64 had (temporary) migration paths. The x86->x86_64 path was pretty easy; x86 apps were still supported for a rather long time. The PPC->x86 migration path wasn't as clean, but they did ship Rosetta for a couple of years before ditching it. If they do Intel->ARM they'll need some sort of migration strategy. Would that involve a Rosetta 2.0?
