Sony had said that it hoped to sell 5 million units by the end of March after releasing the Playstation 4 on November 29 in United States, Western Europe and Latin America and rolling it out across other Asian countries since then.

The console will go on sale in Japan on February 22, the last country currently scheduled to handle the device.

Microsoft Corp said in January that it had sold more than 3 million of its Xbox One console by the end of December after it was also released in late November.
