Sony: 1.2M PS Vita, 2M Vita games sold worldwide

How does that size up to the 3DS and PSP?

Spurred by a week's worth of strong sales in Europe, Australia and North America, sales of the PS Vita topped 1.2 million worldwide this week, Sony Computer Entertainment announced this morning in a press release.

The PS Vita launched in Japan on Dec. 17, selling 321,407 units in the first two days there, according to Famitsu. But sales quickly dropped off bringing in about 400,000 total sales for 2011.

Software sales around the globe for the Vita also saw a spike with the expanded launch of the portable, with worldwide numbers hitting 2 million, according to an SCEA release.

"PS Vita was designed to deliver the ultimate portable entertainment experience, and we couldn't be more thrilled with the reaction we're seeing from consumers and the pace at which PS Vita is selling," Andrew House, president and group CEO, Sony Computer Entertainment, said in a prepared statement. "The market has responded and there is clear demand for a mobile device capable of providing a revolutionary combination of rich gaming and social connectivity within a real world context. To sustain momentum, we're working closely with 3rd party developers and publishers to ensure the best games and franchises possible will be available on PS Vita, and our software line up for the remainder of 2012 will have something for everyone across the globe."

It's difficult to directly compare the launch of the PS Vita to the PlayStation Portable or Nintendo's 3DS because all three portables had staggered roll-outs around the world. But it looks as if the PS Vita may have slightly outpaced the PSP's launch.

The PSP sold 200,000 units in Japan the first day, while the PS Vita sold 321,407 in the first two days. In North America, the PSP launch was a bit weaker than the Vita's as well.

The Nintendo 3DS sold 371,326 in the first two days of its launch in Japan. It sold about 400,000 in its first week in the U.S.
