Also, it would be cool to hear any of those missing five characters or get some idea of what they'll be like in the dub. I could see Canada being left out as a joke and Cuba and Sweden aren't too prominent for the seasons, but Finland appears in a few different episodes so that's odd (unless it's a dual-cast role).
