Gamers are going to have to wait a little longer for the much-anticipated PlayStation 3.
Sony says it's pushing back the rollout from spring to November, citing problems finalizing the next-generation of disk technology.
Wednesday's announcement came at a hastily arranged news conference in Tokyo after word of the delay surfaced in a number of newspapers.
PlayStation 3 has been viewed as crucial to Sony's profits and brand image and the delay is regarded as a major setback.
The development triggered a sell-off of Sony stock Wednesday.
It lost 1.8 % of its value on the Tokyo Stock Exchange.
Sony's video-game chief says the delay involves copyright protection technology for the Blu-ray disc format being adopted for the Playstation 3 and Sony's next-generation high-definition video.
