Sony plans to announce next week that it will introduce a 3D television set sometime next year, the Wall Street Journal and the Financial Times reported today (Wednesday), citing persons familiar with the matter. Details were sketchy, but both financial newspapers indicated that Sony plans to disclose its 3D plans at the IFA consumer electronics show in Berlin. The WSJ noted that Sony hopes the 3D sets will enable its TV unit to dig itself out from under five straight years of losses. The FT quoted from the address Sony chief Howard Stringer is expected to make at the show "The 3D train is on the track and we at Sony are ready to drive it home."
