Hardware sales breakdown for the last two weeks based on the Famitsu numbers found in this article:
Switch - 52,171/31,300
PS4 - 21,448/8,555
3DS - 7,373/2,978
Vita - 406/682
Vita production has ended in Japan, so that's why the console's sales don't follow a normal trajectory of decline after Golden Week. Its weekly sales depend first and foremost on people making up their minds to buy one while they still can.
