Looks like a vierra-type race to me. Even look at the face, the nose specifically, you can see how big and shapely it looks. And bunnies have different shaped ears. You don't think character creation is going to have a variety of ears to choose from. Also, bunny ears are flexible, having a drape type head-dress, over a veirra's head, would weight the ears down to how they look, in that screenshot. And it would make more sense that a agile flexible rabbit-like race would be the pre-lude to getting ninja & samurai. Than a heavy clumsy dragon type race.
Just to get the brains working with imagination, here you go:
^ this is the same thing people where spewing when they(fanbase) said 2 classes were going to be released at launched. And no one believed.
Yoshi said it himself, in an interview or live letter, that the 1st expansion was already near completion(this was early -mid last year). bottom line we don't know what goes on at SE HQ and how fast developers work. They give us controlled information to build hype. Which makes us think they are working slow and dont have time to plan out new classes/jobs.
You would be silly to think that SE does not have and is already working/planning for the 2nd expansion.
Your not going to give all your product to someone that is hook on it. You will feed them little by little, to keep them coming back for more.
