Is it too early for Nintendo to release Wii fit in Europe? GTA IV concerns

[Rock_on_2008]

Game releases on other consoles are irrelevant in deciding on whether or not Wii Fit should be released.
BTW MK Wii releases 2 days before GTA 4 in Europe. 27 April 2008. MK Wii on its own is reason enough to purchase a Wii.
