I think it's possible that there could be a couple more new villagers but I don't think there will be new animal types. When they released the hamster villagers they made a big deal about it in the directs and since we haven't seen anything about that yet it makes me doubtful we will.
i remember a while back people said that japanese twitter said that there were like 50 new villagers or something. or they gave out the total number of villagers and compared to new leaf there's 50 more. all i know is that there's most likely multiple new villagers.
I think there will be a lot of new villagers that we haven't seen yet! There's no reason for them to show each one off right away before release. I don't think we will get new species of animals though, sadly.
from wild world to city folk they brought a few back from GC and we got like 18 completly new villagers? From City folk to new leaf they gave us 100 villagers, a few comeback villagers included. But we got there new personalities and 2 new species aswell. So I think we don’t get as many as before. Let it be 2-3 new per personality, we would have 16-24 new villagers. So I think this is realistic. Everything whats above that is welcoming
I really like the cat with heterochromia mainly because one of my cats also has it.
Other than him, I'm not all that interested in any of the the new villagers.
I hope they release some more in future updates.
I think there will a couple of more new villagers - maybe even a new species in New Horizons. Nintendo almost always leaves in a few surprises, they don't reveal all the details of what you'll find in the game - only enough to hype consumers into buying the game they want to sell. My favorite new villager, so far, is the grey cat with heterochromia iridis. I don't mind if there aren't that many new villagers, since I already have a vast list of favorites, but it'd be a nice treat if more are revealed.
