Some of the higher end home-NAS's have already moved from arm/ppc -> x86_64[1]
Unless ARM64 starts appearing at a low enough price point, I wouldn't be 
surprised to see the smaller vendors do a similar move just to stay competitive.
(probably while keeping 'legacy' product lines for a while at a cheaper pricepoint
 that won't take bigger disks).
