HOLLYWOOD — Sony plans to debut its much-anticipated third version of the PlayStation console at the E3 conference in May.Sony Computer Entertainment prexy Ken Kutaragi confirmed the plans Monday. Given the time it’s taken Sony to move previous consoles from their first public showing to release, that would mean PS3 will most likely enter the market in early 2006. Competitor Nintendo, meanwhile, is planning to release its next console, Revolution, at E3 as well. Microsoft hasn’t announced its plans for the second version of Xbox but will quite likely join in the E3 hoopla. All three companies are believed to be adding multimedia capabilities to their next-generation consoles, such as home networking, TiVo-like digital video recording and broadband Internet connections.
