Piss off with the personal insults. If you can't have a debate without calling people names, then you can go fuck yourself.
There's not a single OLED 4k screen on the market yet. Of the major TV manufacturers I think only LG and Samsung even have a single regular HD OLED model each. 4K OLEDs have only just been unveiled and won't come to market until next year. So it's kind of hard to compare what you can't even buy yet with a dying technology.
And now you're saying that Panasonic IS stopping R&D on plasma technology. Can't you make up your mind? Do you really think they're going to continue to produce big, heavy, power hungry televisions when cheaper, lighter, more energy efficient LED technology is already surpassing plasma picture quality?
Panasonic says they will continue production to at least 2014 and I bet they stop completely once their 4K models come to market, because plasma technology will never exist as a 4k model, at least not from Panasonic and the price point on 4k is going to come down dramatically in the next year.
Trust me when I say I've been in a few TV showrooms in the last year and I'm perfectly capable of seeing that higher end LED screens are amazing and I wouldn't buy plasma for the aforementioned reasons.
Besides, the OP wanted an 80" screen, and as far as I know the biggest plasmas are 65", at least they are from Panasonic. Maybe other manufacturers make bigger ones, I don't know.
