CVG understands that UK PS4 sales outstripped Wii U's lifetime total in a matter of hours following the release of Sony's new console last week.
Retail monitor Chart Track said on Monday morning that PS4 has become the fastest selling console in UK history. While specific sales figures weren't revealed, retail sources have since claimed Sony moved over 250,000 consoles within 48 hours.
Despite launching one year prior to Xbox One and PS4, Wii U may now been relegated to third place in terms of next-gen UK hardware sales.
In late November, UK Xbox One sales hit 150,000 units in the console's first 48 hours of availability, just a few thousand units short of Wii U's total UK sales since release.
At the end of Nintendo's second fiscal quarter ended September 30, global Wii U hardware sales stood at 3.91 million units.
Sony said PS4 sales hit one million units in the console's first 24 hours of availability following its North American release on November 15.
And worldwide Xbox One sales topped one million units in the 24 hours following its November 22 launch, according to Microsoft.
