I believe we'll see more Regional Variants on the next gens and remakes. Remember they're not referred to just as "Alolan formes", but also as "Regional variants".
I wouldn't be too surprised if we got, for example, A-Sandshrew and A-Vulpix in Sinnoh. I mean, they've retconned a few thing on ORAS (like Wally's Gardevoir, Megas and Primals, part of the plot, etc), so changing that wouldn't be too Farfetch'd.
