Sony Computer Entertainment president Andrew House recently said that pre-orders for the company’s brand new portable gaming console, the PlayStation Vita, have sold out in Japan ahead of its December 17th launch. “I’m pretty confident… that there will not be major challenges in meeting demand, even though there may be short-term,” House explained to reporters recently. As the Associated Press points out, a successful launch in Japan could help soften the blow of Sony’s predicted fourth consecutive annual loss. The PlayStation Vita was originally announced during E3 2011 and we were impressed with the gaming performance during our early look at the device. The Vita will launch in the United States on February 22nd for $249.99, and a second version compatible with AT&T 3G will be released at a later date for an additional $50.
