VGChartz Writes: "This week Sony has been celebrating the 20th anniversary of the PlayStation with releasing a PSOne inspired PlayStation 4 and many games have been on sale for the PlayStation Network.
The PlayStation 4 Black Friday week sales are out now. The PS4 had a strong Black Friday week in the US selling 554,350 units for the week ending November 29, 2014, according to VGChartz.
To compare, this is well above anything the PlayStation 3 managed to sell Black Friday week in the US in its lifetime. The PlayStation 3's strongest Black Friday week in the US was in 2009 where it sold 417,864 units."
