There are some reports from the UK that LG Electronics are promising to release a 31" OLED TV in the UK in 2011 (which is not really news) and a 55" TV in 2012. It seems a bit optimistic, and in any case LG thinks that 'commercially priced' OLED TVs will only arrive in 2013. So even if they do release a 55" panel in 2012, it will probably be very expensive (the 31" panel that is planned for March 2011 is said to cost around $9000...).
