Can we expect more new pet models?

I've been looking through Petopia, as I'm a pretty obsessive pet hunter. I noticed there weren't a ton of new pets coming in. The ones I've noticed are the dog, foxes, monkeys, shale spiders, and a couple new skins.

So, what I'm wondering is: Is this all there is going to be for Cataclysm? Or can I expect to see more tameable models in the new zones that aren't open yet?
