If we are talking about best start then the question is focused on which console will have the best sales sustaining software, that is the Wii, face it, whether you care for the games or not, Wii is going to keep selling like gangbusters thanks to games which appeal to the nongamers, Wii fit is selling out constantly in Japan, expect big sales in the West as well, and then Mario Party nine will be out in the summer which will be another major sales boost.
Kart will also be huge considering how well the DS version sold and that the GCN version was one of its biggest sellers, and SSBB was the other big GCN seller, so expect high sales on the Wii.
whetehr you like the games or not is irrelevant, in terms of sales sustainment, Wii has the lead
