I really applaud Bandai Namco on this decision. When Family Ski was first shown off, everyone thought it would be a perfect match for the Wii Fit board. Up until now we had no idea that game would support it. Now this new promo bit shows that the board is indeed supported. It is unclear whether the game fully supports the board, or only uses it for specific portions of the game. I still Bandai Namco deserves a pat on the back, no matter what the outcome.
Unless I am mistaken, this would be the first third party game to support the Wii Fit board. Huge thanks to Creamsugar for the heads up!
