That would be pretty cool, though I don't expect we'll see too many of those guys at once. With the rate of new characters, I'd expect 1 or 2 at a time.

2ch's "unrepresented characters" thread seems to have anons hoping Portugal or Luxembourg will be next, or Indonesia for another new Asian nation.
