Over the holiday season, PS4 and XBox One were essentially tied for number of console sales.The January sales report from NPD shows that the PS4 sold 2X the units of the XBox One. Of course, both consoles are dramatically down from their "can't keep the shelves stocked" pace over the holidays with PS4 selling 280K units vs. XBox One's 145K units.Microsoft had an interesting response to the NPD report pointing to the fact that the when you factor in Xbox One and Xbox 360 both, then Microsoft leads. How Yusuf Medhi, the Marketing head of Microsoft, interpreted the NPD report in the company’s favor is beyond me. What about PS3 + PS4 combined?I wonder if this is more about the $100 price delta between the two platforms and people really wondering if NUI (Kinect) has a value prop that is worth the $100?
