Lettuce be cereal. Panasonic's use 25% or less electricity than Pioneer Plasma's, this is the main thing being holding back PQ, tight regulations on Energy Ratings.
Panasonic Plasma's are now a hell of a lot thinner, produce a hell of a lot less heat and have a multitude of new inputs and technology inside them, such as Camera's, Skype, Youtube, Iplayer, etc. They also weigh a fraction of their older counterparts.
Everybody knows had Panasonic not have to adhere to Energy consumption regulations they would have beaten the Kuro range black and blue years ago.
Also say you do not own a Kuro, do you really want to go out and buy a 6 year old TV which consumes 5 times as much electricity, produces a hell of a lot of heat, weighs more than the moon and has zero warranty? A lot of people cannot afford to blow £4K on a TV right now (recession).
The Kuro is an old, fat, outdated, inefficient machine, it's had it's time, it's glory days are now over.
