Sony's PlayStation Vita portable game machine hits stores in Japan on Saturday, with the company predicting great sales. The device is a touch-interface and motion-sensitive handheld - essentialy a successor to the PlayStation Portable. Gamers can connect over cellphone networks and Wi-Fi hotspots, and use GPS location-tracking technology. The device is also equipped with front and back cameras, a touchscreen in front, a touch pad on the back and two knob-like joysticks. PS Vita will also enable gamers to play against each other using PlayStation 3 consoles over the PlayStation Network.

Sony hopes that a successful debut would help the company offset the rest of its struggling business.

Vita is expected to compete with Nintendo's 3DS gaming device, which had a disappointing start despite the company's efforts to market its 3-D technology ,mainly due to lack of games.

Sony plans to offer more than 24 game titles with Vita's introduction, including "Uncharted: Golden Abyss," "LittleBigPlanet," and "Wipeout 2048."

The Vita's Wi-Fi only model will cost $249.99 in the U.S. and euros 249.99 in Europe. The Wi-Fi and 3G-enabled Vita will retail for $299.99 and euros 299.99.

Nintendo's 3DS retails for about 40 percent less than the Vita in Japan.

The PS Vita goes on sale in North America and Europe on Feb. 22.
