Sadly, a price and date have not yet been announced.
The new KNF559500 from Samsung is something that certain people have been waiting on for a long time now. It's one of the first OLED sets to be released in a reasonable size and, hopefully, a price range that's not too far out of the budget.
Samsung has given their 55 inch OLED the full Smart TV treatment, equipping it with a quad-core processor, Smart Hub access, gesture controls and everything else the company's 2013 sets are getting. The big difference is, of course, the OLED tech behind it, which should provide much improved video quality.
The KNF559500 also supports multi-view, which allows two users wearing 3D glasses with built-in headphones to watch two different things at the same time.
