For Sony Corporation, a tech industry also-ran, the moment of reckoning is here. The first three generations of PlayStation sold more than 300 million units, pioneered a new style of serious video games and produced hefty profits. PlayStation 4, introduced by Sony on Wednesday evening, is a bold bid to recapture those glory days.

The first new PlayStation in seven years was promoted by Sony as being like a "supercharged PC." It has a souped-up eight-core processor to juggle more complex tasks simultaneously, enhanced graphics, the ability to play games even as they are being downloaded, and a new controller designed in tandem with a stereo camera that can sense the depth of the environment in front of it.

The console itself was never shown during the two-hour presentation. No release date was given, although before Christmas holidays is a possibility. No price was mentioned.

With PlayStation 4, serious games are about to become much more social. A player can broadcast his game play in real time, and his friend can peek into his game and hop in to help. Also, players will be able to upload recordings of themselves playing and send to friends.

These and other new features cannot hide the fact that PlayStation 4 is still a console, a way of playing games on compact discs that was cool when cellphones were not smart.
