Infoscout's finding are very interesting, because several of their articles cite PS4 clearly winning at several stores and that significantly fewer people shopped at Target and Walmart this year: http://blog.infoscout.co/category/findings/
They essentially discredit their own data and their analyses disagree with other published data, so it might really come down to sample size. How do they find their audience? Let's put this all in perspective, as there were 150 million shoppers this BF, and 33% of them shopped online: http://www.cnbc.com/2015/11/30/holiday-sales-perfectly-average-so-far-analyst.html
That means their receipts represent 0.2% of all shoppers and 0.3% of brick and mortar shoppers, so there's a little wiggle room in those numbers.
