Electronics hardware makers Tuesday showed off snazzy new devices enabling motion-sensing play and 3D effects, intensifying a battle to introduce video-gaming to a new generation of casual users. Hot on the heels of Microsoft Corp's full-body motion-sensing Kinect, Japan's Nintendo Co Ltd on Tuesday took the wraps off a new version of its DS handheld device that can play games and show movies in 3D without glasses. And Sony Corp introduced the “Move” - which like Nintendo's popular Wii employs a wand-like controller to double as everything from a tennis racket to a baseball bat in games - and promised up to a score of 3D titles soon for its PlayStation 3 console. The launches and demonstrations from the triumvirate of gaming hardware makers at this week's E3 expo in Los Angeles - the $60 billion industry's most important annual showcase - set the stage for a pitched battle to bring players beyond the hard-core fanbase into the fold. Analysts said Microsoft made the biggest splash with a seemingly revolutionary platform that employs no controller, and a clear mandate to target casual players. And Nintendo's move to add a third dimension to its market-leading DS mobile handled device will shore up its market position. The triumvirate that rules the market for gaming devices is stepping up their battle just as the industry is beginning to recover from a two-year slump. Analysts say laggard Sony, the erstwhile consumer electronics leader that has seen Nintendo surge ahead with the well-received Wii, has a potential winner in Move but that the jury was still out. Sony's Move appeared to mimic a gaming system that Nintendo pioneered with the controller-operated Wii a couple years ago, but Sony argued the precision of its technology - which captures every twist and contortion of arm actions - and the ability to employ combinations of buttons will continue to please hard-core players. Another innovative technology highlighted was cloud gaming - the hosting and playing of games on servers without the need to buy and store a game from a home device. Cloud service OnLive announced titles including Ubisoft Entertainment SA's Assassin's Creed and Electronic Arts Inc's Mass Effect 2, stored on Dell Inc servers and played - via cellular connections on computers and eventually TV. New gizmos On Tuesday, the creator of Super Mario games and the Wii offered a peek at its 3DS. The device comes with two screens - one a touch screen - and three built-in cameras, enabling the machine to snap digital photos in 3D. Nintendo, which has seen growth in sales of its industry-leading Wii slow as rivals slash prices, did not say when sales begin or give a retail price, except that it will hit store shelves sometime before March 2011. Nintendo is not alone in taking the wraps off a hot new gizmo. On Monday, Microsoft said it will begin selling its “Kinect” motion-sensing game system on November 4. Also on Tuesday, Sony announced that its Move motion-sensing platform - which will compete with the Wii and Kinect - will begin selling on Sept. 15 in Europe, followed a few days later in the United States. Sony executives said the Move's wand - which has buttons for in-game functions - ensures the platform appeals to as wide a range of players as possible, both casual and hardcore users. Sony is making a huge bet on 3D gaming, as it is on 3D televisions, arguing it is unique in offering an end-to-end experience, from TVs to content via its entertainment division. It will have over 20 3D titles available for the PlayStation 3, which has a base of 35 million users, by March of 2011.
