Of course, we always expected as much. Preorders for Nintendo's fitness title were sky-high in Blighty, with the game pretty much selling out before it even appeared on store shelves. Even so, the record-breaking success of Wii Fit may have surprised the most optimistic of Nintendo executives.

Over the weekend, Wii Fit became the sixth fastest-selling UK videogame of all time. That's an impressive achievement for any title -- until you remember that the Wii Fit bundle costs almost as much as two games (£70). Then, the achievement stops being merely impressive, and becomes jaw-dropping. It also set a new record as Nintendo's fastest-selling game ever in the UK, beating out poor old Mario Kart Wii, which held that particular title for ... two weeks. Ouch.
