Given the current YTD sales greater than 20% lead, and that even NS strongest weeks usually affect its sales by quite less than 20%, while in normal weeks it easily outsells it, and that even after NS launch weekly sales were very often up YoY, it will most probably match 2016 sales and very likely outsell them (NS doesn't directly compete with PS4, but when in stock and easily available it competes for an overlapping group of impulse buyers that decide at the last minute which console to buy).
