Did Nintendo miss a huge opportunity with the year headstart they have on MS / Sony?

[Mr Khan]

In the short term it will appear so, however, unless Nintendo seriously drops the ball, their advantage will be apparent heading into this holiday. They'll possibly have a price drop, have a wave of 2nd-generation software against the competition's first-generation software. Imagine Wii's holiday 2007 lineup clashing toe-to-toe with 360's holiday 2005 or PS3's holiday 2006

Granted, it's highly possible that Sony and Microsoft will aggressively run a better class of launch title, which will complicate the question
