PS3 sold 14.3m units in its peak year (2011).
PS4 is at 12.9m at the moment, with 3 more weeks to go. It should easily sell the extra 1.4m and surpass PS3's peak year in its first year on the market.
Amazing feat, considering PS3 was $249, had a slim model and was a mature console with hundreds of successful games. The PS4 will still sell more with much less going for it.
