Although NeXTStep ran on x86, the MacOS build on x86 was John Scheinberg's personal skunkworks project until it became Marklar in 2001 (and then kept under the hood for another four years). Mind, Darwin was always written to be portable, but it wasn't a deliberate strategy to take it to Intel. This time around though, I too reckon that they have already a MacBook running on an A10X in the labs.
