The Science Corner

Sony Corp. executives showcased the benefits of the company's upcoming PlayStation 3 console saying its technological features will give it an edge over rival products from Microsoft Corp. and Nintendo Co. Sony executives again touted what they claim are competitive advantages, such as the PS3's speedy "Cell" processor, the console's Blu-ray disk format for high-definition video and an online network that will include video chat and micropayments.

Compared to the previous models, says CBS News Technology Analyst Larry Magid, the new game consoles being unveiled this week are dramatically better, as manufacturers show off some real advances in technology. "The graphics are much more vivid and lifelike and the action is noticeably more realistic," says Magid, adding that Sony has a lot riding on PlayStation 3. "Apple has taken away much of the market for Sony's WalkMan products and even though Sony's flat panel TV sales are going very well, the company does have some serious competition when it comes to high-end TVs." The PS3, which was originally set to debut this spring, is now expected in the fall. Key information such as the exact launch date, price and games lineup have not been announced.
