With the apparent success of Wii Fit in the UK adding to strong Japanese sales and the upcoming American release, I am predicting that Vgchartz will show a higher total for Wii Fit worldwide than GTAIV's Xbox 360 and PS3 versions combined on January 1st, 2009.
I believe that Wii Fit will be massive. It will be a change of magnitude in game sales. The attach ratio of it will approach Wii Play.
