Sony is currently selling an 11 inch OLED TV (XEL-1) for about $2,500. This TV is more like an expensive executive desk decoration than a home entertainment product. Sony's COO Stan Glasgow said this week at a dinner event in San Francisco that Sony is "awfully close" to selling a 27" OLED TV.
What "awfully close" means in terms of time frames can only be guessed. I assume though that Sony will try to sell a 27 inch OLED TV this holiday shopping season, at least in Japan.

The biggest problem in producing OLED TVs lies in the amount of manual labor needed according to Sony. After the 27 inch OLED Sony plans to offer a 40 inch OLED TV.
