It looks like Sony still has bragging rights that the PlayStation 4 is the top-selling console. Not to be outdone by the latest NPD report, the PlayStation Twitter account announced that the Sony's new console is still outselling the Xbox One, for the sixth month in a row. Yesterday, Microsoft said that following the Xbox One's $100 price drop it'd seen a "strong spike in interest" and sales of the console jumped by "more than double" the previous month. It's worth noting however, that Redmond didn't release specific sales numbers for May and, to be fair, neither did Sony. The latest report from the NPD Group plays it a bit vague, too, but says that combined sales of the PlayStation 4 and Xbox One were higher than combined totals for the PlayStation 3 and Xbox 360. What's more, compared to last June, hardware sales saw a 106 percent increase overall. Sales of home consoles combined represented a 200 percent jump compared to last year, which is likely due to the two new consoles being available.
