Ars Technica's Ben Kuchera gets critical of the the 360 units sold tally: "Microsoft has sent word to the gaming press that the Xbox 360 has become the first console in the current generation to sell 10 million units in the US. Microsoft also points out its 19 million units sold worldwide but, while the company thinks there is much to be proud of in these numbers, these milestones aren't quite as conclusive as Redmond would have us believe."
