Ubidays: Rayman Raving Rabbids 3 With Balance Board?

A new video on the Rayman Raving Rabbids site shows the lovable rabbits with a balance board. Possible hint that Ubisoft is going to announce Rayman Raving Rabbids 3, with balance board support at their press conferences this week? Or just a funny video?
It seems like a good direction for the game to go, especially if competition(WarioWare is rumored to use the balance board in it's next game) is starting to use it.

You can find the video HERE.

Ubidays runs from May 28-29 in Paris.
