I think each continent having their own royalty is fine. It just makes sense. Some people/neopets don't even visit the other areas, so they wouldn't come in contact with the other ruling families.
I would love to see more wizards and such, but the thought of more witches gets me nervous. I have a feeling that instead of cool, benevolent witches, they'd be worty, mean ones. lol
What I would like to see is more regular folk. There are shop keepers and royalty and mystics and such, but I'd like more random neopets that you could talk to or do little quests for or play a game with or whatever. Maybe one where if you visit a special time throughout the day (random like turmy), you can get one random stat raised or something. Maybe another that you can play a game against. Not a game you can get to in the games room, but only through this neopet. Then you can play checkers, nine man's morris, or some other two player game against that neopet. Maybe a hidden neopet that randomly switches between houses/huts/tents/whatever in that world throughout the day and if you find them you get 500 np or something.
I think more randomness and regular neopet characters are what the worlds need. Something to liven them up a bit and make players want to explore them more instead of just clicking on their dailies and moving on to the next one.
