The Playstation 4 has not only become Sony's fastest selling console, but the fastest any console has ever reached 1 million units sold. These numbers only come from North America (US/Canada), the PS4 will be released in Europe on November 29th and Japan on Febuary 22nd, 2014.
PS2 - 3 days to ship 1 million units,
Wii-U - 1 week - 400 000 console sold
Wii - 8 days - 600 000 console sold
Playstation 3 - 2 months - 1 million console sold
Xbox 360 - 2 weeks - 326,000 console sold
Sony Computer Entertainment president Shuhei Yoshida has confirmed these are units sold, rather than what has just been shipped.
Earlier this week Jack Tretton said he was predicting 3 million sales by the end of 2013 and Sony is aiming to sell 5 million units by March 2014. With Europe's and Japan's launch right around the corner, I have no doubt they will be able to reach these numbers.
