Both Samsung and Panasonic will be flogging 3DTVs in the US by the end of the month, but don't expect to see anything from Sony until June at least. Details on the LX900, HX900 and HX800 do sound tantalizing however.

Japan will start selling the sets on June 10th, with the rest of the world expected to follow suit sometime soon after. Already Sony's making the bold claim that they'll be much cheaper than Panasonic's 3DTV sets—in Japan, anyway.

Akihabara News attended the press launch of of the LX900, HX900 and HX800 3D sets in Japan, which are all of the "monolithic" design, and came back blushing with the news that the LX900 series is the one to aim for. It'll be comprised of four models, all with the Intelligent People Sensors, which adjusts the sound and brightness depending on where people are sitting. It builds on the VE5 TVs launched last year, which could detect when you leave the room, so the TV turns off automatically.

The LX900 will be available in 40, 46, 52 and 60-inch LED-backlit options, will have inbuilt wireless LAN, and include two sets of 3D active shutter glasses (which will be available in grey, blue and pink options). The 46-inch size will reportedly cost 350,000 Yen—about $3,900.

Only 46 and 52-inch options will be available for the HX900 series, which will be LED-backlit, and feature Intelligent MPEG noise reduction. Less attractive, the HX800 eschew the Intelligent People Sensors and MPEG noise reduction, and come in just 40 and 46-inch sizes. [Akihabara News via Reuters]
