Can Mario Kart Wii sell more than GT5P on first week?

[Gamerace]

It may beat GT5:P but only because it's a prologue and not the full game, plus Wii has a larger user base.

Lifetime MK will easily smoke GT5P but GT5P will have a much bigger percentage of it's sales in it's first week than MKWii so it wouldn't surprise it if GT5P opening week is bigger.
