With a whole week including Black Friday, it's hard to believe first week numbers won't be above 500k. That said, it depends on Nintendo's shipments, and consumer apetite. Usually it takes a while for consoles to have good weekly numbers till they're established, so Wii U could have had an average Black Friday (See Wii and 360 second and third week numbers in US). I'll still go with 500-600k.
Edit: I change my mind. I'll go with 683k
