While PS4
sales were up across the board week - on - week thanks to the Holiday shopping
season and the solid performance of Yakuza Kiwami 2 and Earth Defense Force 5 (ranked respectively 1st and 2nd with 131, 931 units and 111,075 units sold) this still was not enough to catch up with the Switch, that is
booming thanks to regular shipments finally hitting the local shelves, with 164,908 units sold during the past week.
