Microsoft today announced that it has sold over 5 million Xbox One consoles to retailers around the globe, but sales of the system have still lagged behind rival Sony’s PlayStation 4. By comparison, Sony revealed on Wednesday that PS4 sales had topped 7 million in sales to consumers.

March US sales estimates from NPD put the PS4 in first place for hardware sales for the third month in a row. Both Microsoft and Sony (inFamous Second Son, Titanfall) saw major exclusives released on their platforms last month. Titanfall’s combined Xbox One and PC release took the top spot in game sales, according to NPD, with inFamous Second Son in second.

While we expected to see a bump in sales of Xbox One units due to the Titanfall bundle, Microsoft is continuing to fall behind. It’s still early for this generation’s console war, but the Xbox One will need a few more hit titles to catch up.

Microsoft’s new Xbox head recently admitted that the company had made mistakes with the launch and renewed his commitment to putting “gaming first” on the console.
