Wii Fit U has toppled off the spring/summer balance board and will now be released sometime this winter, Nintendo's Satoru Iwata announced this afternoon.
Apparently Nintendo wanted to create new features for the game that required more time. Maybe it's now a hover board or indeed a hoover board, which would be equally useful.
Nintendo also announced that Wii Party U will be out later this year. It has 80 different mini-games you probably don't care about as well as Tabletop Minigames you can play entirely on the GamePad. It's magic.
