As for Xbox One sales, I still think theyre gonna shift over a Million in the weekend. They will claim a bigger launch and record revenue, though numbers will be skewed by the "worldwide" launch.
As for the topic at hand, I dont think we will find out until NPD. It will be over 1 Million units in America by the end of the Month, quite easily. I dont think its gonna break the Million barrier there in a day or week though.
