Sony's thunder on these sets was already felt over in Berlin, but there's nothing quite like official verbiage saying that a 9.9-millimeter thick HDTV (and one with 240Hz technology) will be coming to the good 'ole US of A. Alongside Blu-ray HTIBs and a pricey new BD deck, Sony's also formally introducing the 52-inch BRAVIA KDL-52XBR7 and 40-inch BRAVIA KLV-40ZX1M here at CEDIA. The former features the eye-testing Motionflow 240Hz frame rate tech, which promises to deliver "exceptional motion detail in movies, sports and video games." It also boasts the outfit's BRAVIA Engine 2, an 80,000:1 contrast ratio and compatibility with BRAVIA Link expansion modules. As for Mr. Thin, it features a 1080p panel, an edge-lit wide color gamut LED backlight, a single HDMI input and support for Sony's BRAVIA Wireless Link. Both sets should ship in December for undisclosed prices, but you can read up on the full array of specifications just after the break.
