It has been estimated that PS4 sold 66 per cent more units than Xbox One in the US in November.
Michael Pachter has said in his most recent investor note that he believes PS4 sold 1.25m consoles in the region throughout the month and that Xbox One sold 750k.
Note that PS4 was released in the US on November 15th, giving it a week more on the market than Xbox One which launched on November 22nd.
If correct, that 66 per cent margin mirrors what was seen in the UK during the console's respective first weeks – Xbox One sold 150k units while PS4 managed 250k, a 66 per cent difference.
Pachter added that Wii U is expected to have suffered significantly as a result of the launches, with hardware sales falling 65 per cent year-on-year. Xbox 360 and PS3 sales are predicted to have fallen 44 per cent and 28 per cent respectively.
