PlayStation 4 is Amazon UK's fourth best-selling gaming product of 2013, according to the site's official best-sellers list, with Xbox One limping in at no. 70.

The console has also re-overtaken Xbox One in Amazon's hourly best-sellers list, after Xbox One saw a brief surge in sales following this week's DRM changes.

Official pre-order numbers for either console have yet to be revealed, but it's believed by many that Microsoft altered its DRM policies after the product struggled to attract reservations.

Both consoles go on sale this Christmas, with an update on Amazon US pinning a November 27 release date on Xbox One.
