we've seen all of the new HDTVs, it's time to find out when they're actually going on sale, and for how much. HDGuru has just dug up advertised pricing for some of the new models from Sony (BX, EX and HX lines) and Sharp (640, 745, 844, 847 and 945), while US pricing and ship dates for Panasonic's new plasmas have been revealed by Value Electronics. For Samsung, some of the new HDTVs have already showed up for preorders at retailers like Vanns, including the top of the line 75-inch ES8000 priced at $7,999, while a more reasonably sized 46-inch model is $2,699. Sony's prices range from $399 for the KDL-32BX320 to $2299 for the KDL-55HX750, while Sharp's range from LC-46-L540U for $1,099 to the LC-80LE844U for $6,499. Most of the ship dates are still TBA, although Panasonic is planning to unleash the ST50 later this month, followed by the UT50 and GT50, then the top of the line VT50 in May.
