According to a post on VGChartz, Sony has hit two significant milestones in recent days, while Microsoft have their own milestone to celebrate too.
According to the site 15 million PlayStation 4s have been sold worldwide (up to the week ending November 22), and they also suggest that Sony has now sold more than 57 million games for the console.
It's not an official announcement from Sony, but if accurate, it's good news for the firm nonetheless. Late last month it was reported that they had sold 13.5 million console, so given the time of year it's certainly plausible.
Another report from the same site includes their estimation that Xbox One has sold over 8 million units worldwide, with a further 32 million games sold for the platform.
Again, these are estimates, not official numbers, so take them with a pinch of salt. Even if they are accurate they don't take into account the recent Black Friday sales. No doubt Sony, Microsoft and Nintendo will do well in the coming weeks.
