Sales of Xbox 360 in the UK doubled last week off the back of the launch of Kinect, Eurogamer has learnt.
The spike was confirmed this afternoon by sales monitor Chart-Track, a spokesperson stating that, while specific figures could not be revealed, it was "more than a fair reflection" to say the figure was double that of the previous week.
The boost is understood to have widened substantially the gap between Xbox 360 and PlayStation 3, with Sony's biggest hope for a pre-Christmas surge coming next week with the release of the long-delayed Gran Turismo 5.
A senior publishing source added: "360 doubled last week and it was already selling a lot. Wii and PS3 have been beaten by 360 consistently over the past few months.
"Wii is still outselling PS3 – the numbers are going the wrong way for Nintendo year-on-year but it's certainly not a disaster."
Kinect went on sale last week both separately and as part of official hardware bundles, the latter likely to be responsible for the jump in numbers.
Microsoft revealed yesterday that over one million units of Kinect has sold worldwide in the ten days following its 4th November US launch.
The US giant reckons it's on track to sell five million units by Christmas.
