Sony Bravia XBR-HX909

Sony's XBR-HX909 (or HX900) TVs come in 46" and 52" in size, use intelligent dynamic (local dimming) LED backlighting, and has optional USB wireless adapters. The TVs support 3D, but you'd need to buy Sony's active shutter glasses and 3D transmitter (the emitter costs around $50, and the glasses $150 per pair) - unlike the LX900 series, in which they come bundled.
