PS4 once again king of U.S. console sales for June 2015

For the second month in a row, the PlayStation 4 was the top selling console in the United States, according to the latest NPD Group report.

Though Sony has regularly outsold the Xbox One since both consoles released in November 2013, Sony attributed the latest feat "to the overwhelming popularity of Batman: Arkham Knight PS4 bundles."

Given that Rocksteady's Batman: Arkham Knight was the top-selling game for the month of June, with the PS4 version recording the "highest sales for a single SKU across any Batman game since NPD has been tracking the industry," it's not a surprise the PS4 was the best-selling console once again.

Unfortunately, hardware bundles weren't included in the NPD's report for software sales, but if they had been then Arkham Knight would be the best-selling game of 2015 so far.

Overall, total video game sales for June came in at $869 million, with video game hardware sales totalling $313 million, up 8 percent from June 2014.
