LG's ginormous 72-inch LZ7900 to make its debut on store shelves, but the rest of CES's primo 3DTV crop is rearing to ride out, with Sony's HX929, HX820 and HX720 series of LED-backlit LCD screens and LG's Infinia PZ750 plasmas now priced at Amazon. 3D-Display-info.com found Sony's locally-dimmed Bravia sets starting at $2,099 for a 46-inch HX720 with Gorilla Glass protection, all the way up to $3,799 for the premium 55-inch XBR-55HX929 with a full-array LED backlight. Meanwhile, the 50-inch LG PZ750 (with Smart TV, naturally) starts out at $1,599, while a 60-inch version of the same thing will run $2,199. Which one fits best in your den? That depends on a number of things, but we will add that the Sony sets are merely up for pre-order, while the LG units are listed as shipping within a matter of weeks.
