So Xbox360 sold better in 2012 US in spite of not being #1 on Amazon.
If you add up the 8-10 different Xbox 360 SKUs in Amazon's system that would have been sold that year it probably was. All that list tells us is single SKU sales. Xbox 360 is offered with or without hard drive, with or without Kinect, plus there are a number of Holiday game bundles they do every year, all of which are listed individually.
