Korea Times posted an article in which they say that both Samsung and LG won't be able to start producing OLED TVs in 2012 - as both company are facing technical issues and very low yields. Both companies intended to launch the OLED TVs in time for the Olympic games in London (August 2012) - but obviously they failed to do so. Last month Digitimes reported that LG won't be able to launch in 2012, and now we hear that Samsung won't start producing either.
The article actually says that DisplaySearch expects the companies to start producing TVs in 2012 - but only a handful. 500 units, in fact - that's hardly mass production. In July, DisplaySearch estimated that the two companies will sell 20,000 units in 2012 - which is also a very low amount.
