The OLED beat Plasma in contrast and black level but not in color accuracy, they both beat LCD by a mile. The Plasma is also MUCH cheaper than the OLED at this point though that'll probably change.
I also note they are calling the LCD sets "LED" which I'm pretty sure only refers to the back lighting.
Have they solved the longevity issues with OLED yet?
