Will sell 400k WW and blow everybody away again next week. People have been waiting for this to happen for months across the globe, surely they are not all satisfied yet and they wont wait until holidays either. Sony will sell 2 million PS3's in September alone easily.
Sony sold 500-600k PS3's in 4 days and no retailer are complaining about being supply constrained. Go back and carefully read some of the GDC 2009 Sony Rep interviews on the $299 announcement reaction/exceptions, they clearly expected this to happen, their survey are surely telling them something that we don't know, its not like Sony are taking shots in the dark here.
I think people are underestimating the brand and Sony's ability to summon up 15 years of experience selling the PlayStation, just like they underestimated Nintendo.
