Considering changing out my 2010 midrange Sony tv for a new one. Nothing wrong with it but with the higher end thin bezel tvs I can squeeze a 50 inch into the space of my 46 inch. The only real spec boost is better contrast and higher refresh rates. How long until oled, and 4k tvs trickle down to us mere mortals? It seemed like there is a Paradigm shift coming in tvs based on ces coverage this year. I don't want to plunk down the money if there are new tvs right on the horizon. My next tv will be on the higher end, but I dont want to spend 20k. Anyone have thoughts on the ultra high definition roadmap. Will I regret getting a sweet tv today within say the next 2-3 years?
