I keep hearing about the imminent demise of plasma, but Samsung recently said they feel plasma will be around until at least the year 2020. I agree. While LCD has gained popularity for a variety of factors, it's not for everyone, and can't replace plasma in all situations. Motion resolution, gaming input lag, 3D ghosting, and off-axis viewing problems are still major factors. Other LCD issues include clouding, and screen door effect, which some people find unacceptable. By the way, I am not bashing LCD. I am just pointing out why LCD would not an acceptable replacement for plasma for some people.
I feel Samsung has based the year 2020 on their projections for OLED ramp up. It will take quite a few years before OLED can be price competitive with plasma.
