Agree that they'll have devs submit ARM builds and all that. fwiw, the reason I think the co-processor idea is likely is that Apple has recently re-committed to the Mac and specifically some niche use cases therein (thus they can't fully ditch Intel), and that they're already shipping an A10 equivalent in Macs today (the T2) so not that hard to go a bit further into the water. Also, in single core perf its possible the ARM chips would exceed most Xeons they ship, which clock lower in favor of more cores. Agree if Apple had its way and could pick its markets perfectly, they'd have slowly shed niche use cases in favor of the highest margin markets (which is mainstream not pro), and thus at the appropriate moment dumped Intel and gone all-in on ARM. However, they're seeing the traditional pc market only moves so fast, there's many many pro niches they didn't really consider enough, and those niche Mac users really do have a lot of indirect value to Apple's brand. Emulation wouldn't cut it for those users - it'd only work if Apple saw ditching those markets as an acceptable tradeoff. Intel CPUs are expensive but so are GPUs, and they'd only be bundled in the higher end machines - nothing that's below $2500-3000. Well, that's my hunch anyway.
