Despite Microsoft's efforts to put a good spin on the Xbox One since its launch, the company is well behind market leader Sony when it comes to game console sales.
But this year the Xbox has a chance to reclaim the title of the industry's best selling video game system, thanks to a series of software delays on the part of rivals Sony and Nintendo—and a few key exclusives on Microsoft's.
As best as anyone can tell right now, Sony's PlayStation 4 is still eating the Xbox One's lunch, putting together an considerable sales lead in the U.S. The PS4 has sold more than 20 million units worldwide, as of March. Microsoft, meanwhile, hasn't given an update on Xbox One sales since last November, when it hit 10 million.
Even with what was said to be strong sales last holiday season, when Microsoft cut the price of the Xbox One, there's still likely a significant gap between the two.
(IHS Technology, in an estimate sent before the start of E3, forecasts the PS4 will have a worldwide installed base of 34 million by the end of the year, versus just 20 million for the Xbox One.)
But Microsoft has undeniably made progress. The Xbox One system has sold better than its predecessor in the same time frame, and the company has course-corrected when fans didn't embrace early features.
