Yeah, there are bits that just sound too awkward when you put historical context into them (like the partitions).

As for the anime: Unless they adapt that one strip where America's referred to as Alfred in a commercial, or Spain's "April Fools" thing (which I don't think would work for an adaptation with all the meta), I don't think there's much chance of seeing the human names referenced. Turkey, Japan, and S.Korea had their names referenced there, if I remember correctly.

People like to say "well Himaruya removed his post so he never intended the names!", but the fact is, he removed all of his '07 update logs when '08 came around. And then Bamboo Thicket v.1 went under a few months in, and that's where he posted Canada and Belarus's human names. So it's not like he deleted just the things related to the names, just anything he considered "old". He's been known for doing a lot of this, especially to his pre-Hetalia series D:.

But with that being said, I don't think it's likely we'll see more human names unless someone asks him again and he just so happens to find that request/mail and answer it. It'd be interesting if Ukraine and Liechtenstein got names.
