MK may not beat GT5's first week. Look at MK DS's first week sales, they are good, but not AMAZING. MK is a legs machine. I do not think MKWii will do more than 1 million WW first week. The only way it could is if Nintendo actually tries to hype it, which they ussually don't for MK.
Lifetime MK Wii will beat GT5 WW, europe will be the only place where GT5 might win, it is really a toss up.
MK:DD sold near 2 million on a userbase of under 5 million in Europe.
GT4 sold 5 million of a userbase of 40 million.
It will be interesting to see what the affect of the drastically different userbases will be.
MK could easily do 4 million this gen in Others, and it is yet to be seen if the PS3 will have large enough userbase to support the kind of sales we saw last generation in Europe.
But for now I am predicting 4 million for MK, 4 million + for GT5 in Europe.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
