Panasonic Still Pushing Plasma, Adds 3D Capability
Other than the size, the specs appear identical, at least from what we can translate from Panasonic Japan's press release. Both sets require that you don a pair of active shutter system 3D glasses, which is pretty much a requirement for all large screen 3D sets now and in the immediate future.
Panasonic rates the displays with a 5,000,000:1 contrast ratio and both offer DLNA support, Skype compatibility, HDMI connectors, SD card slot, video-on-demand support, and a bunch of other goodies.
