Although it's been a while since we've had any official figures, it's common knowledge that the PS4 is ahead of the Xbox One in terms of sales.
Microsoft has been willing to adapt and change its strategy with the Xbox One, but does the company believe it can catch up with Sony's machine?

When asked by Eurogamer if the Xbox One could catch up with the PS4, Microsoft's Phil Spencer said that actually, the combined userbase of Xbox One, Xbox 360 and Windows has never been bigger.
"I honestly don't goal the team on how many units Sony sells," he said.
"I think about what we're going to do, and how many Xbox customers we have across 360, Xbox One and Windows - thinking about the combined community of people on Xbox and playing those games, and that number's never been bigger."
Spencer said that the company is in it for the long run, and that the console's lineup is incredible.
"There are ways to sell consoles by losing more money on hardware and building an unnatural business construct that I'd never want to do," he continued.

"At the end, when people make a commitment to Xbox and the consoles they buy, the games they buy, they want to know that Microsoft and Xbox is in it for the long run.
"To sacrifice the long term for any short term gain doesn't make any sense. I really focused on our first-party investment, and you see it showing up in 2015 and 2016. Next year's line-up is pretty incredible, and we haven't even talked about all the games that are coming next year."
Microsoft discussed many of its first and third-party exclusives at gamescom, including Quantum Break, Scalebound and Crackdown 3.
However, it will have a tough time catching up with the PS4, which has a 90% market share in some parts of Europe.
