PlayStation 4 is estimated to have sold around 1.25 million units in the US during November - around half a million more units than the Xbox One, according to predictions made by Wedbush Securities analyst Michael Pachter.
"We expect hardware sales of 1.25 million PS4 units and 750,000 Xbox One units in their debut month," reads Wedbush's November 2013 NPD Preview report.
PS4 launched in the US on November 15 and achieved global sales of 2.1m by December 1, with 700,000 said to have been sold outside of North America. Xbox One launched in 13 territories on November 22, and sold-through over one million units at launch.
The report forecasts Wii U sales of 150,000, 700,000 Xbox 360 sales and 550,000 PS3 units.
Forget about the Xbox One and PS4; Wii U's 150,000 is a staggeringly low number for a current platform in the biggest shopping month of the year.
