Gamers are gearing up for a huge announcement from Sony. On Wednesday, the entertainment and consumer electronics company is expected to announce the highly-anticipated successor to the PlayStation Three video game console, at an event in New York City. There hasn't been a new console released from Sony in seven years. Since then, Microsoft's Xbox has taken the lead in the U.S., with Nintendo's Wii a competitive third. Globally Sony is still the number one console maker, but that may also be shifting as people are turning more and more to downloading games on their smartphones and tablets. Some sources believe the next generation of PlayStation will have new enhancements including the ability to play games streamed over the internet as well as games stored on discs.
