PlayStation 4 sold one million consoles on day one. And so has Xbox One, Microsoft has bragged. Described as "the biggest launch in Xbox history," the company promises to "replenish stock as fast as possible to meet the unprecedented demand."
While selling a million units is nothing to scoff at, do keep in mind that PS4 only launched in one market (America), while Xbox One launched in 13. Sony will launch in Europe on November 29, with a greater Asian roll-out to continue throughout December.
