Sony has sent out an estimate of the number of PlayStation consoles sold worldwide between November 18th and December 31st 2011.
The Vita contributed 0.5m towards the total number, with the PS3 exceeding 3.9m. The PlayStation Move sold 1.7m, whilst the good old PSP still managed to chalk up a respectable 1.6m.
Oh, and the PS2 is still going, selling 0.5m. A good set of figures for Sony.
