Alongside Sony’s upcoming 3D-capable LCD sets, the company has announced standalone shutter glasses and an infrared emitter to drive them. For a family of four, the 3D upgrade would cost $587.

Sony’s TDG-BR100 and TDG-BR50 active shutter glasses will cost about $133 this June in Japan. The emitter will run about $55. (Prices converted from yen.)

Keep in mind, if you buy Sony’s flagship LX900 TV, starting at $3900, you get the emitter and two sets of glasses “free.” But clearly, Sony’s money making strategy is as much, if not more on the peripherals than it is on the televisions themselves. While their glasses may be a higher quality than others in the industry—a reasonable possibility—at least one manufacturer assured me at CES that their shutter glasses would cost about 1/4 Sony’s current asking price.
