Sony has released its official 2009 holiday sales numbers, and they claim that they were able to move 3.8 million units of the PlayStation 3 worldwide, with 1.7 million of those PS3s being sold in the U.S.

The company is crowing that this is a 76% improvement, leading to the best holiday season sales of the PS3 so far. Sony claims that these sales prove that the PlayStation 3 is gaining momentum, and as a result the company will be looking to expand the PlayStation Network as part of their future strategy.
