According to NPD analyst Liam Callahan, "March 2013 saw deep declines of 32% in dollar spending for dedicated video game hardware, with stronger declines for portable hardware than for consoles. However, sales for the Nintendo 3DS grew 9% over last March. In March 2013, the Xbox 360 had the highest hardware unit sales for the 20th month in a row.”
Last March sales were 225k so that would put the 3DS at 245k then.
I thought the 360 was #1 for 27 months in a row......
