I'm thinking Apple will drop a couple x64 cores into an Ax chip. Maybe they license from AMD. Probably impossible, but I wonder if something clever could be done at the microcode level (mostly) so that a core could switch instruction sets. The Apple ARM instruction set would be the native, optimized one, but the x64 IS would run acceptably.
