Sure, we might all just be getting used to LED-backlit LCD HDTVs, but this train ain't stopping, Chico -- Samsung just got official with the 8500 series, which features the next-generation of local-dimming LED backlights. The 54.6-inch and 45.9-inch 240Hz sets are just 1.6 inches deep and offer a 7,000,000:1 dynamic contrast ratio, a 2ms response time, and an Energy Star 3.0 savings mode that continually adjusts the picture and backlight to optimize both picture quality and power savings. You're also getting Samsung's usual suite of connected TV features, like the Yahoo! Widget Engine, DivX playback, and DLNA support, but you'll be paying handsomely for all this newness -- the 45.9-inch UN46B8500's MSRP is $3,599, while the 54.6-inch UN55B8500 will run you $4,499.
