The most important pieces of the puzzle being a "new deep encased cell structure, crystal emissive layer and first surface colour filter." What that means is the new sets, part of Project Kuro ("Black" in Japanese) have a black level 80% deeper than 7th generation Pioneer plasma. Without any sacrifice in brightness, according to our sources. That deeper low end gives the TV an overall 20,000:1 contrast ratio, which should take care of some of the issues, if not all, that I had with a current generation plasma I faced off against a top line Sharp LCD.
The TVs also have an "Optimum Mode", which sounds like an advanced ambient light compensation system. In other words, it'll alter the picture output according to both the source's light patterns, as well as the lighting in your living room. I wonder if it can adjust white balance and color to compensate for the hues given off by your lava lamp collection.
The high-end 50" and 60" 1080p HD models have the 20000:1 contrast ratio, the "lower-end" 42" and 50" variants only have 768p HD and a 16000:1 contrast ratio. They will all be available in June.
