To be honest, while I do agree with Nintendo's words on the project, I do think that considering the amount of processing power Natal is supposed to drain from the 360, the Wii would have taken a much larger hit.
Ultimately, there's no point in sacrificing like 30-40% of your processing power, especially for something you don't think will be all that good.
