Sony’s Bravia line seems to have been around for donkey’s years at this stage but they keep churning out new models, the latest two 3D offers arriving this week with a “monolithic” design and concealed touch-screen controls.

The Bravia NX813.

The new NX713 and NX813 are both due for release later in 2010 and come complete  with dynamic edge LED backlighting, with Motionflow 100Hz Pro on the NX713, and Motionflow 200Hz Pro on its buddy.

Sony tells us that “3D capability, connectivity and elegant design” are the three main selling points here and Sony’s press release on the matter revealed, in addition to full high definition 3D, both sets feature Bravia Internet Video, “for on-demand, online entertainment.”

“With 3D capability, the connectivity of Bravia Internet Video and stunning monolithic design, the NX713 and NX813 are perfect for people who want both style and performance from their TV,” Christian Brown, senior category marketing manager with Sony UK said.

TechRadar picked up on one peculiarity though: “Somewhat strangely, consumers will need to add a 3D Sync Transmitter and glasses to get the 3D experience, with these not being provided out of the box.”

Seems like a bit of an own goal to us as when buying online most people don’t expect such (admittedly minor) complications to go 3D. In fact seeing as how Sony, Panasonic and others have been bending over backwards to try and get as many people as possible on the 3D train the need for a transmitter and the lack of glasses seems very strange indeed.

Okay, it won’t cost you the world to get the glasses but with plenty of 3D-ready models coming to market it can be the little things that turn people off.

Content-wise, the Sony press release added that “all 3D Bravia TVs are supported by a rapidly increasing variety of 3D content”. Asked to name names, the missive continues says this ‘variety of content’ includes “the latest Hollywood movies on Blu-ray 3D disc such as Sony Pictures Home Entertainment’s ‘Cloudy With a Chance of Meatballs’; sport, music, natural history and entertainment from new 3D cable and satellite channels; even 3D games such as ‘WipEoutHD’ and ‘MotorStorm Pacific Rift’ for the PlayStation3.”

Sony commented that Bravia Internet Video will let you watch catch-up TV services and YouTube without the need for a PC, “plus exclusive content like the FIFA World Cup Collection and streaming movies from Lovefilm.”

Sony is still to confirm exact release dates and pricing for the UK and Ireland.
