There's no reason why the TV shouldn't work as a standard HD model, too - in fact, it will have to, as very little material will be available in 3D.
Actually, there's nothing special about the TV itself - it's down to the source component, the software and the specs.
Have seen dems of both 'with specs' and 'no specs' 3D in Japan and Korea last year: the former was striking with some Olympics footage and just plain distracting with a music video and some CGI, but made my wife feel distinctly queasy; the latter looked interesting at first glance, but the 3D effect collapsed as soon as you moved just a smidge off the 'sweet spot' viewing position.
