Engadget had the chance to get up close and personal with the recently-announced 9mm-thick Kuro plasma concept at CES, with Paul Meyhoefer, VP of Marketing and Product Planning, and Tony Ueda, Worldwide Manager of Display Technology, demoing at the Pioneer booth the night before the show floor opens. Pioneer gave the grand tour of two new technology concepts, with "advanced design" and "extreme contrast" displays. Pioneer has always claimed to target the high-end home theater enthusiast, and this 50-inch Kuro concept plasma shows that off in spades, being 9mm (0.35 inches) thick at the glass and only 24mm (0.94 inches) thick at its widest point. As seen in our gallery below, there is not even a hint of input ports or other distractions from its 40 pounds of sexy svelteness. We held up a BlackBerry Curve 8320 next to the plasma's glass, and dwarfed it with a whopping 15.5mm (0.6 inches) of depth.
