Well, the Armors in Divintiy were also not "Racial" armors but each armor appeared differently on each race because each of them had a distinct visual theme.
This is less true in DnD, but it also depends on the artist.
In some editions certain races have very strong aestheitcs to them.
I also dont think its gonna happen, but its a possibility.
as for racial archetypes, well, i somehow dont think well get to that.
