The eighth-generation video game consoles followed PlayStation 3 and Xbox 360.
GameStop, which reported a 30.2 percent drop in new video game hardware sales in the fourth quarter ended Jan. 31, expects older hardware sales to fall more than 50 percent in 2015.
The company is betting on PS4 and Xbox One software and mobile sales to make up for weak demand for consoles.
