E3 2015's all to play for, but Sony will have one victory to parade in Los Angeles next week: the May 2015 NPD. After a shock defeat in April, the Japanese giant has responded by immediately turning the tides; the PlayStation 4 was not only the best selling system of the month in the United States, but it also moved more software than its rivals, too.

"As we head into E3, we would like to thank gamers for making PS4 the top-selling console and the leader in software sales in the U.S. in May," a chuffed Sony spokesperson told GamesBeat. "We are truly humbled by this success and we look forward to sharing what's next for PS4 at our E3 press conference on 15th June."

While the PlayStation maker may be punching the air, it wasn't a particularly positive month for the industry as a whole – despite the release of heavy hitter The Witcher 3: Wild Hunt. Overall spend in the physical space tallied just $507.6 million, down a whopping 13 per cent year-over-year. Software dipped the hardest, tallying $204.7 million compared to $273.9 million the year prior.

However, hardware was also down by 18 per cent, totalling just $153.6 million. Price drops to the Xbox One may partially be to blame here, but it's more likely that CD Projekt Red's open world adventure wasn't able to move as many systems as Watch Dogs, which launched amid much enthusiasm in May 2014.

Despite that, Geralt of Rivia's escapade did come in at first, bullying both Mortal Kombat X and Grand Theft Auto V into the second and third positions respectively. MLB 15: The Show continued to lurk around the top ten, finishing in ninth this time, while FIFA 15 enjoyed an end of season boost into eighth. Not bad for a country that supposedly doesn't like soccer.

It's perhaps no surprise to see the PS4 back on top; last month always looked like a blip, and insider reports claim that it lost out by a negligible amount to begin with. Batman: Arkham Knight has been heavily associated with Sony's system, so it's hard to see June going any other way. It needs to keep its foot on the gas at E3 2015 if it wants to maintain this momentum, mind.
