To put that into perspective, the PlayStation 4 (NASDAQ: SNE) has shipped 7 million units in total as of April 6th, 2014 and Nintendo's Wii U has shipped 5.86 million units as of December 31, 2013. The Wii U launched on November 18, 2012 and has had a full year's head-start on Microsoft and Sony; these sales figures led to major losses for Nintendo, who reported an expected loss of $240mm for 1Q14. The company previously reported that it expected a $536 million profit.
As for Microsoft, the recent earnings call voiced that the Xbox One would cease entirely or significantly slow in manufacturing output. This is expected for a console entering its second year of life -- demand has dropped from 2013 -- but there's no argument that Microsoft has been thoroughly lashed by Sony thus far this generation. Microsoft CFO Amy Hood indicated a "channel inventory drawdown for Xbox consoles," which translates to a slowing or cessation of actual manufacturing of units due to surplus in stores.
For the curious, the previous consoles have shipped in these counts:
- Xbox 360: 80 million, as of October, 2013.
- Playstation 3: 80 million, as of November, 2013.
- Wii: 100.9 million, as of December, 2013.
