Panasonic's welcoming you to the future of plasma HDTV, starting along with the stunning 150-inch 4K plasma, that is, surprisingly enough bigger than its old 103-inch model (shocking, we know) leading to the debut of three "super thin" plasma prototypes measuring 24.7mm deep in 50-inch and, for what it claims is the first time, 58- and 65-inch sizes that also include Wireless HD. One-fourth the thickness of current Panasonic models and one-half the weight combined with no wires leads Panasonic to believe we'll be able to reorganize the living room shortly, without silly mounting issues and need to run cables. If that fails to inspire, how about a 42-inch prototype that claims twice the luminance efficiency and the same brightness as its current 42-inch 1080p model while only sipping half the power -- if that's a concern. Check out more pics after the break.
