Nintendo's Hideki Konno, in charge of the 3DS hardware since 2008, has repeated that the company's next home console will surprise people. He did not confirm that 3D was planned for home consoles, of course. Previously, though, various Nintendo executives and producers made similar statements.
In a 45-minute interview with me, Konno said that simply transferring the 3DS' visual experience to a home console would not be enough. He also expressed doubts about peripherals needed for viewing 3D visuals, referring to glasses and proprietary screens alike. You will remember that Nintendo toyed with the idea of offering a separate autostereoscopic screen for the Gamecube, but canned the idea.
Konno went on to state that the strength of the 3DS was in offering 3D visuals out of the box. Also, its portability allowed for others to experience the device easily. When pressed about cooperations with movie studios, he could not confirm whether full-length 3D movies will be available on the console. So far, only movie trailers have been announced.
