It's strange... Before Xmas I had seen tons of TV commercials featuring Wii Fit U, in Amazon France it's available since 13th December it seems, but it has never appeared in any chart. Your thoughts? Did everyone become slim enough with the first Wii Fit?
It was only a partial release before Christmas, and most people who will be getting it that way will probably be using the special deal Nintendo gave to those who already have a Balance Board - download the "demo" version, buy a Fit Meter, and it unlocks the game fully, so long as you have a Balance Board.
This makes it far cheaper than the regular Retail version. And it's effectively a digital distribution version. So unless they're tracking the sales of Fit Meters (which they probably aren't), it won't show up on charts. Note that I'm one of the people who made use of the deal.
