I think that there should be a lot of new animals, if not just a fully new roster of animals to replace all the ones we know/love... but that would upset plenty of fans, so adding new animals would be the way to go.
however, this is nintendo, and they've already made two animal crossing games that haven't added a noticeable amount of new villagers/artificial intelligence, so why would they change now?
hopefully they'll add new animals, and a LOT more text/context/speaking lines for the villagers, but I doubt that it will be a lot, if any is added. we'll probably get a dozen or so animals of a new species, and no one will notice because they still haven't encountered all of the animals from the original game, IMO. unless, of course, they play it a lot, in which case the thought of revisiting all of the animals again in 3d will be a huge selling point, I'm sure, and there'll hopefully be some more new things (hopefully some new types of items of some sort) to keep everyone happy, nitpicky or not.
yes, there needs to be more. *crosses fingers*
