Newsbrief: Yesterday, Sony announced that the PlayStation 4 has sold 7 million units at retail -- meaning put them in the hands of consumers. Today, Microsoft shared its numbers, which are less rosy: 5 million Xbox Ones have been shipped to retailers. The company did not specify what percentage of that stock has been sold through to consumers. The company was quick to point out that the console's sales are outpacing the Xbox 360's at the same point in its lifespan -- by a robust 60 percent -- but didn't address the gap between its sales and Sony's. Of course, Microsoft's box is more expensive than Sony's -- it's $100 more in the U.S., for example. It has also shipped in far fewer territories. Notably, Sony has shipped its next-gen box in Japan, but Microsoft has not.
